2022-09-22soc/intel/spi: Move BIOS flash SPI controllers to fast SPI driverWerner Zeh
There are two classes of SPI controllers on Intel chipsets: * generic usable SPI controllers * SPI controller hosting the BIOS flash (fast SPI controller) While the first class can be used for generic peripheral attachment the second class mostly controls the BIOS flash and a TPM device (if enabled). The generic SPI driver is not fully applicable to the fast SPI controller. In addition, the fast SPI controller reports the reserved MMIO range used for the BIOS flash mapping so that the OS is aware of this range. This patch moves the fast SPI controller of all known SoCs to the fast SPI driver in common code. In addition, the PCI device for the fast SPI controller is removed from the function 'spi_soc_devfn_to_bus' as this is a callback of the generic SPI driver.

2021-10-26soc/intel: Update api name for getting spi destination idWonkyu Kim
Update api name and comments to be more generic as spi destination id is not DMI specific. Update api name as soc_get_spi_psf_destination_id and comments. And move PSF definition from pcr_ids.h as it's not pcr id.
