Pass boothowto from the bootloader to the kernel by adding a
openbsd,boothowto property under /chosen.

change marks[] array to uint64_t, so the code can track full 64-bit
details from the ELF header instead of faking it.
Proposal from mlarkin, tested on most architectures already

Make arm64 efiboot can boot from partitions other than "a".

Pass the physical address to the end of symbols to the kernel. From
armv7 we inherited the mechanism to manually modify the kernel symbol
table to change the value of esym. We don't use this, but instead use
the virtual address that is passed to the kernel. This change makes us
only work on and hand out physical addresses. Bump the efiboot version
to make this ABI change more visible.

Since turning of the MMU in the beginning of the kernel removes
the caches' contents, we lose data about the freshly copied and
created kernel. This leads to bootup failures. Make sure to
clean the caches to make sure that the data is in memory before
we turn off the MMU.

whitespace fixes

We are supposed to be mapped on a 128 MB block, so skip the first
few bits to calculate a valid virtual address for esym.

FreeBSD aarch64 code. Hard work done by Dale Rahn.
