efiboot: Use 1:1 PA to VA mappings for RT services.

UEFI firmware on Snapdragon X Elite devices crashes when
SetVirtualAddressMap is called with runtime mappings that are not 1:1.
Always do this on arm64 as it won't interfere with KVA and will help us
avoid avoid a very common class of firmware bugs.

Allow an MD check in prepare_boot and use it on arm64 (aarch64) to check

data accesses at EL0 via ID_AA64MMFR0_EL1.BigEnd.

Update to support EFI runtime outside the kernel virtual address space
by creating an EFI RT pmap that can be activated / deactivated when
required.

Adds support for EFI RT to ARM_MMU_EXTENDED (ASID) 32-bit Arm machines.

On Arm64 the usage of pmapboot_enter is reduced and the mappings are
created much later in the boot process -- now in cpu_startup_hook.
Backward compatiblity for KVA mapped RT from old bootaa64.efi is
maintained.

Adding support to other platforms should be easier as a result.

Add support for the boot services watchdog and pet it on every block I/O

add bi-endian support to the libsa ufs reader and enable it in efiboot.

ffs frontends to "ufs.c" now also define ufs_dinode_swap, ufs_indp_swap,
and FS_MAGIC (moved from ufs.c #if segments.) these are used to call
the right (32/64 bit) ffsv1/v2 version.

ufs.c 'struct file' gains f_swapped member. accessors for d_magic,
d_reclen, and d_ino are introduced (they need to be swapped.) sfter
reading an inode from disk, read_inode() may call ufs_dinode_swap().
indirect block number and caches may be swapped.

error handling in ffs_find_superblock() is cleaned up. (size is slightly
reduced on some ports with this part.)

defaults for new defines added to ufs.c. (XXX: we build ufs.c but i think
all the consumers don't use it, and we can stop building it.)

LFS support is not included.

add a cut-down copy of ffs_bswap.c from the kernel.

also enable bi-endian disklabel support in efiboot.

most ports build and sizes compared for platforms that don't enable this
code and all but one saw reduced code size. booted several platforms with
new boot code.

Implement rndseed support in efiboot and fdt arm.

The EFI environment variable `rndseed' specifies the path to the
random seed. It is loaded only for fdt platforms at the moment.

Since the rndseed (an rndsave_t object as defined in <sys/rndio.h>)
is 536 bytes long (for hysterical raisins), and to avoid having to
erase parts of the fdt tree, we load it into a physical page whose
address is passed in the fdt tree, rather than passing the content of
the file as an fdt node directly; the kernel then reserves the page
from uvm, and maps it into kva to call rnd_seed.

For now, the only kernel that does use efiboot with fdt is evbarm,
which knows to handle the rndseed. Any new kernels that use efiboot
with fdt must do the same; otherwise uvm may hand out the page with
the secret key on it for a normal page allocation in the kernel --
which should be OK if there are no kernel memory disclosure bugs, but
would lead to worse consequences than simply loading the seed late in
userland with /etc/rc.d/random_seed otherwise.
