cmd_dhry.c: Use lldiv for vax_mips calculation as well

Since dhry_per_sec is a u64 we must also use lldiv here when working
with it.  Otherwise:
../lib/dhry/cmd_dhry.c:(.text.do_dhry+0xd8): undefined reference to `__udivdi3'

On some platforms.

dhry: Correct dhrystone calculation for fast machines

At present samus reports about 5600 DMIPS. With the default iteration count
this is OK, but if 10 million runs are performed it overflows. Fix it.

Add a dhrystone benchmark command

Drystone provides a convenient sanity check that the CPU is running at full
speed. Add this as a command which can be enabled as needed.

Note: I investigated using Coremark for this but there was a license
agreement and I could not work out if it was GPL-compatible.
