Bump MAXDSIZ to 2G on armv7. Needed for llvm-16.

Bump KVA space up to 512MB (and a bit).

ok phessler@, deraadt@, miod@

Set VM_PHYSSEG_MAX to 32 and use VM_PSTRAT_BSEARCH as the sort/search option
like we do on macppc and sparc64. This makes our kernel recognize all the
memory on the Odroid XU4.

ok jsg@

Use the same stack size as on i386

ok kettenis@ deraadt@

Make ARM_KERNEL_BASE explicitely unsigned

Raise VM_PHYSSEG_MAX to two and load an additional physical memory
segment if u-boot reports it. Needed for the utilite where u-boot
reports two 1GB segments of physical memory.

From Patrick Wildt in bitrig with some additional sanity checks added.

VM_MAX_KERNEL_ADDRESS is the end of the kva range not the end of
addressable virtual memory space but arm ports were using a value of
0xffffffff for this.

Instead of using a shared VM_MAX_KERNEL_ADDRESS define add md
VM_KERNEL_SPACE_SIZE defines based on the KERNEL_VM_SIZE values
from the respective machdep.c files.

djm's novena was hitting "panic: bufinit: can't reserve VM for buffers"
without a similiar change.

In the future, we shouldn't have one port port ARM SoC, that's just
ridiculous. This is the first step for a common and generic ARM port
for ARMv7 SoCs.
