soc/amd/common/block/lpc: Refactor ESPI Setup

ESPI is setup in two different locations in bootblock depending on early
port80 routing configuration. Also ESPI is setup in PSP, if verified
boot starts before bootblock. Consolidate all the scenarios by
initializating ESPI as part of lpc_early_init if verified boot starts
after bootblock and ESPI is enabled.

BUG=None
TEST=Build and boot to OS in Guybrush. Perform S5->S0, G3->S0, warm
reset and suspend/resume cycles for 50 iterations each.
