ec/google/chromeec: Add minimum delay between SPI CS assertions
Some Chrome OS ECs require a small amount of time after a SPI
transaction to reset their controllers before they can service the next
CS assertion. The kernel and depthcharge have always enforced a 200us
minimum delay for this... coreboot should've done the same.
BRANCH=gru
BUG=chrome-os-partner:58046
TEST=Booted Kevin in recovery mode, confirmed that recovery events got
logged with correct timestamps in eventlog.
