soc/amd: add and use fch_enable_hpet_decode

On Picasso we missed setting this bit in coreboot and since the default
after reset is 0, we had to rely on the FSP to set this bit. Stoneyridge
and Cezanne have the HPET decode enable bit in the same position in the
same register. In the ACPI table entry written by
southbridge_write_acpi_tables the HPET entry gets added, so we should
make sure that we enable the decode.

TEST=HPET still works on Mandolin.
