mainboard/google/reef: Ignore SPI IOSTANDBY
SPI controller need to access flash descriptors/SFDP during s0ix exit,
so all fast SPI IO can't be put into IOSTANDBY state. For reef, that
will be FST_SPI_CLK_FB, GPIO_97, GPIO_99, GPIO_100, GPIO_103 and
GPIO_106.
BUG=chrome-os-partner:61370
BRANCH=reef
TEST=Enter s0ix state in OS, after resume run flashrom to read SPI
content.
