This patch adds a remove function to the Intel ICH SPI driver, that will be called upon U-Boot exit, directly before the OS (Linux) is started. This function takes care of configuring the BIOS registers in the SPI controller (similar to what a "standard" BIOS or coreboot does), so that the Linux MTD device driver is able to correctly read/write to the SPI NOR chip. Without this, the chip is not detected at all.
