Match other architectures and print CPU information during
cpu_startup(). In particular, this prints the information after the
message buffer is initialized which allows it to be retrieved after
boot via dmesg(8).
While here, add some extern declarations to <machine/md_var.h> in
place of duplicated declarations in various source files.

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.
Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

This was enumerated with exhaustive search for sys/eventhandler.h includes,
cross-referenced against EVENTHANDLER_* usage with the comm(1) utility. Manual
checking was performed to avoid redundant includes in some drivers where a
common os_bsd.h (for example) included sys/eventhandler.h indirectly, but it is
possible some of these are redundant with driver-specific headers in ways I
didn't notice.
(These CUs did not show up as missing eventhandler.h in tinderbox.)

This is an amalgam of a patch by Doug Ambrisko to
generalize uart_acpi_find_device, imp moving the
ACPI table to uart_dev_ns8250.c and advice by jhb
to work around a bug in the EPYC 3151 BIOS
(the BIOS incorrectly marks the serial ports as
disabled)

* handle (inefficiently for now) meeting padding and alignment requirements for
transmit mbufs.

This is required for FDT's standard "reg-io-width" property
(similar to "reg-shift" property) found in many DTS files.
This fixes operation on Altera Arria 10 SOC Development Kit,
where standard ns8250 uart allows 4-byte access only.

As cs is stored in a uint32_t, use the last bit to store the
active high flag as it's unlikely that we will have that much CS.

This commit improves code styles like:
- removing commented code
- format comments as C-style
- add spaces after #define-s
It also bring ability to build kernel without INTRNG and remove RedBoot dependency.

These are older MIPS4kc parts from Atheros. They typically ran at
sub-200MHz and have 11bg, 11a, or 11abg wifi MAC/PHYs integrated.
This port is the initial non-wifi pieces required to bring up the
chip. I'll commit the redboot and other pieces later, and then
hopefully(!) wifi support will follow.
