Add support for GPIO internal pull up/down configuration on RPi4 family.
BCM2711 SoC on 4th generation Raspberry Pi changed the way to configure
its GPIO pins' internal pull up/down resistors. NetBSD already have
support for this change, and port it to FreeBSD is trivial.
This patch, based on the NetBSD commit adds the appropriate method for
BCM2711 and now we can properly configure the GPIO pins' pull status.

The prior implementation of VM_PAGE_TO_PV_LIST_LOCK() performed a
linear-time search of the vm_phys_segs[] array. However, in contrast to
PHYS_TO_PV_LIST_LOCK(), that search is unnecessary because every (non-
fictitious) vm_page contains the index of the vm_phys_seg in which it
resides.
Change most of the remaining uses of CHANGE_PV_LIST_LOCK_TO_PHYS() and
PHYS_TO_PV_LIST_LOCK() to CHANGE_PV_LIST_LOCK_TO_VM_PAGE() and
VM_PAGE_TO_PV_LIST_LOCK(), respectively.
Collectively, these changes also reduce the size of a GENERIC-NODEBUG
kernel's pmap.

[ARM] Check target feature support for __builtin_arm_crc*
`__builtin_arm_crc*` requires the target feature crc which is available on armv8
and above. Calling the fuctions for armv7 leads to a SelectionDAG crash.
```
% clang -c --target=armv7-unknown-linux-gnueabi -c a.c
fatal error: error in backend: Cannot select: intrinsic %llvm.arm.crc32b
PLEASE submit a bug report to ...

Add `TARGET_BUILTIN` and define required features for these builtins to
report an error in `CodeGenFunction::checkTargetFeatures`. The problem is quite widespread.
I will add `TARGET_BUILTIN` for more builtins later.

Fix#57802
Note that programs attempting to use ARM/AArch64 CRC intrinsics, when
they are not supported by the targeted CPU, will still receive a regular
compilation error (instead of a fatal backend error) similar to:

For now a non-native ABI (i.e., Linux) uses the kern_alternate_path()
facility to dynamically reroot lookups. First, an attempt is made to
lookup the file in /compat/linux/original-path. If that fails, the
lookup is done in /original-path. Thats requires a bit of code in
every ABI syscall implementation where path name translation is needed.
Also our kern_alternate_path() does not properly lookups absolute symlinks
in second attempt, i.e., does not append /compat/linux part to the resolved
link.
The change is intended to avoid this by specifiyng the ABI root directory
for namei(), using one call to pwd_altroot() during exec-time into the ABI.
In that case namei() will dynamically reroot lookups as mentioned above.

Perhaps, this does not makes much sense as destroyng %rcx declared by
the x86_64 Linux syscall ABI. However,:
a) if we get a signal while we are in the kernel, we should restore
tf_rcx when preparing machine context for signal handlers.
b) the Linux world is strange, someone can depend on %rcx value
after syscall, something like go.

This change creates a static inline function, BN_check_prime, for
pre-3.0 use which is implemented with the previous (1.1) compatible call
under the covers, `BN_is_prime_ex`.
The `nchecks` parameter value is maintained, even though it has no
noticable behavior change, given that the documentation clearly states
that at least 64 or 128 rounds are executed on the backend, depending on
how many bits there are in the given number being factored out.
