SPI: Fix and enable Fast Read support
- Fix handling of 5-byte Fast Read command in the ICH SPI driver. This fix is ported from the U-boot driver. - Allow CONFIG_SPI_FLASH_NO_FAST_READ to be overridden by defining a name for the bool in Kconfig and removing the forced select in southbridge config - Fix use of CONFIG_SPI_FLASH_NO_FAST_READ in SPI drivers to use #if instead of #ifdef - Relocate flash functions in SMM so they are usable. This really only needs to happen for read function pointer since it uses a global function rather than a static one from the chip, but it is good to ensure the rest are set up correctly as well.
