commit 90ac882a32 (soc/amd/common/block/
spi: introduce SOC_AMD_COMMON_BLOCK_SPI_4DW_BURST) introduced a Kconfig
option to enable/disable the 4DW burst support in the SPI flash data
prefetcher, but missed to update the documentation above the
fch_spi_early_init prototype, so update the outdated documentation now.
