SMM: Add option for SPI driver to be available in SMM
- add Kconfig option for CONFIG_SPI_FLASH_SMM
- compile subsystem and chip drivers for smm if enabled
- change mdelay(1) to udelay(500) since mdelay is not defined
in SMM and a 1ms delay is worth avoiding
- make flash chip structure non-const so the probe function
pointers can be relocated for use in TSEG
- Make SMM PCI access possible in southbridge SPI code
