soc/amd/common/block/lpc: Add config options for eSPI
eSPI on Picasso is configured using the LPC bridge configuration
registers. This change enables config options to allow SoC to select
if it supports eSPI (SOC_AMD_COMMON_BLOCK_HAS_ESPI) and mainboard to
select if it wants to use eSPI instead of LPC for talking to legacy
devices and embedded controllers (SOC_AMD_COMMON_BLOCK_USE_ESPI).
