soc/amd/common: move FCH IOAPIC and HPET init from SMBUs to LPC device
Despite the SMBus device being function 0 of the FCH PCI device, the
MMIO resource of the FCH IOAPIC is on the LPC device which is function 3
of the same PCI device, so move the FCH IOAPIC initialization code to
the LPC device. Since the HPET was enabled in the same function, also
move it to the LPC device initialization.
TEST=On Mandolin both IOAPICs are still correctly detected by Linux.
