Remove the mode_val from the clock definition as it's a bit unreadable.
Use mode_shift to represent which bit control the mode in the register.
Simplify some case where we can avoid a register read before changing it.
Set the PLL back to normal mode after the PLL have stabilized.

When using kldxref on kernel modules built with clang8 + lld8,
kldxref would be unable to find the modules metadata information,
because PowerPC64 was using the ef_nop.c implementation of
ef_reloc().
When GNU LD was used, it was also relocating the metadata section of
the .ko file. LLD does not do this, but only generate dynamic
relocations for it. With minor changes, ef_powerpc.c can now work
for PowerPC64 too.

In the old style, all the children of the device node which did not have a
compatible property were the partitions. In the new style, there is a child
node of the device which has a compatible string of "fixed-partitions", and
its children are the individual partitions.
Also, support the read-only property by setting the corresponding slice flag.
unwrapping multiple lines of code. Also, convert some short multiline
comments into single-line comments. Change old-school FALSE to false.
All in all, no functional changes, it's just more compact and readable.
Summary:
To safely synchronize timebase we need to disable the timebase on all
cores, set timebase, and resynchronize. This adds two new devices, mutually
exclusive, which attach on the SoC simplebus, to freeze and unfreeze the
timebase. The devices are singletons, and platform-specific, so no reason
to make them optional and in separate files.
This was found to be necessary for top(1) to work correctly on an AmigaOne
X5000 (P5020 SoC). It also fixes bufdaemon and bufspacedaemon hangs at
shutdown.
Test Plan: Regression test on various Book-E hardware.

Embedded lzma decompression library becomes a module usable by other
consumers, in addition to geom_uzip.
Most important code changes are
- removal of XZ_DEC_SINGLE define, we need the code to work
with XZ_DEC_DYNALLOC;
- xz_crc32_init() call is removed from geom_uzip, xz module handles
initialization on its own.
xz is no longer embedded into geom_uzip, instead the depend line for
the module is provided, and corresponding kernel option is added to
each MIPS kernel config file using geom_uzip.
The commit also carries unrelated cleanup by removing excess "device geom_uzip"
in places which were missed in r344479.

RockChip clocks register have a write mask in the upper 16 bits, if a 1

Use this instead of always setting the mask to 0xFFFF0000.
This avoids a read of the register.
While here, when switching PLL frequency, first switch it to slow mode.
When set to slow mode the PLL clock will be the external oscillator.
Changing the PLL parameters while its output is used can cause hang (sometimes).

Non-x86 arches use an inconsistently named header for the file containing
"pc" attributes, and the ifdef messes to include the right header were out
of date in the 2 files that I added to the MI files list.
Only amd64, arm, i386, mips, powerpc and sparc64 are supposed to support
syscons. Only arm and mips were out of date in the ifdef. Test
coverage for of syscons in arm is broken (turned off) in NOTES, but
syscons is in some other arm config files which universe detects as broken.
arm64 and riscv remain broken due to the opposite bug of not turning off
sc in NOTES, the same as before r344458 (see r344443).
The header is MD to contain possibly-non-"pc" encodings of attributes, but
since the attributes are essentially virtual in graphics mode and non-x86
arches only support graphics mode, the header has always been the same on
all arches except for different style bugs, so there should be only 1 MI
copy of it for syscons' use. It was used in pcvt and still gives an an
API and an ABI, so it should be public and MI near or in sys/consio.h.
It was first implemented on Illumos and then ported to ZoL.
This patch is a port to FreeBSD of the ZoL version.
This patch also includes a fix for a race condition that was amended

Implement ffs_getpages_async(), which when possible calls the asynchronous
flavor of the generic pager's getpages function. When the underlying
block size is larger than the system page size, however, it will invoke
the (synchronous) buffer cache pager, followed by a call to the client
completion routine. This retains true asynchronous completion in the most
common (block size <= page size) case, which is important for the performance
of the new sendfile(2). The behavior in the larger block size case mirrors
the default implementation of VOP_GETPAGES_ASYNC, which most other
filesystems use anyway as they do not override the getpages_async method.

exit boot services in the MI bi_load() rather than having N copies of the
GetMemoryMap/ExitBootServices dance.
i386 never quite caught up to that; ldr_enter was still being called but
the prereq for that, ldr_bootinfo, was no longer. As a consequence, this
ExitBootServices() was being called with a mapkey=0, clearly bogus, and
reportedly breaking the boot in some instances.
