arch/x86: factor out and commonize HPET_BASE_ADDRESS definition

All x86 chipsets and SoCs have the HPET MMIO base address at 0xfed00000,
so define this once in arch/x86 and include this wherever needed. The
old AMD AGESA code in vendorcode that has its own definition is left
unchanged, but sb/amd/cimx/sb800/cfg.c is changed to use the new common
definition.
