soc/intel/common: Add support for common GSPI controller
Add support for GSPI controller in Intel PCH. This controller is
compliant with PXA2xx SPI controller with some additional registers to
provide more fine-grained control of the SPI bus. Currently, DMA is
not enabled as this driver might be used before memory is up (e.g. TPM
on SPI).
Also, provide common GSPI config structure that can be included by
SoCs in chip config to allow mainboards to configure GSPI
bus. Additionally, provide an option for SoCs to configure BAR for
GSPI controllers before memory is up.
