x86: Add SPI support to quark/galileo
The Quark SoC contains a legacy SPI controller in the legacy bridge which is ICH7 compatible. Like Tunnel Creek and BayTrail, the BIOS control register offset in the ICH SPI driver is wrong for the Quark SoC too, unprotect_spi_flash() is added to enable the flash write.
