soc/amd: move acpi_add_fsp_tables implementation to common FSP code

Since the acpi_add_fsp_tables implementation is identical for all SoCs,
factor it out and move it to the common AMD FSP code. Also guard the
acpi_add_fsp_tables call in soc_acpi_write_tables with
if (CONFIG(PLATFORM_USES_FSP2_0)) to properly handle the FSP dependency.
