soc/intel/cmn/block/smm: Clear SPI SYNC_SS before disabling WPD
This patch follows the BWG recommendation (doc 729123) by clearing
the SPI SYNC_SS bit before disabling the WPD bit in
SPI_BIOS_CONTROL. This prevents boot hangs due to a 3-strike error.
Unable to follow this guideline would result into boot hang
(3-strike error).
