x86, hpet: Simplify the HPET code

Browse source

On 64-bits, using unsigned long when unsigned int suffices
needlessly creates larger code (due to the need for REX
prefixes), and most of the logic in hpet.c really doesn't need
64-bit operations.

At once this avoids the need for a couple of type casts.
