soc/amd: factor out non-CAR romstage to common code
Since the romstage code is very similar between all AMD non-CAR SoCs,
factor out a common romstage implementation. All SoCs that select
SOC_AMD_COMMON_BLOCK_PM_CHIPSET_STATE_SAVE call fill_chipset_state, so
this Kconfig option can be used to determine whether to make that call.
In the FSP case, amd_fsp_early_init gets called, while in the case of an
implementation that doesn't rely on an FSP to do the initialization,
cbmem_initialize_empty gets called to set up CBMEM which otherwise would
be done inside the FSP driver code. Since only some SoCs call
fch_disable_legacy_dma_io again in romstage right after
amd_fsp_early_init, introduce the new
SOC_AMD_COMMON_ROMSTAGE_LEGACY_DMA_FIXUP Kconfig option, so that the
SoCs can specify if this call is needed or not.
