soc/amd/common: Always use genoa SPI MMAP driver

Currently the generic x86 SPI flash mmap driver is being when not
using DMA and when not on GENOA. It only works for ROM_SIZE of 16 MiB
or less and prevents boot when the ROM is bigger than that.

Use the genoa_poc SPI MMAP driver on all platforms by default as it
allows to use a ROM_SIZE greater than 16MiB. The newly introduced
Kconfig SOC_AMD_COMMON_BLOCK_SPI_MMAP is used for all platforms when
the SPI DMA driver is not in use.

This doesn't allow to access the whole SPI flash using the ROM2	MMIO
window,	but it no longer prevents boot when the mainboard specifies
the correct SPI flash size in Kconfig.

TEST: Booted an AMD/birman+ with 64MiB ROM specified in Kconfig.
