src/soc/intel: Provide common block fast_spi_flash_ctrlr
Now that we have a common block driver for fast spi flash controller,
provide spi_ctrlr structure that can be used by different platforms
for defining the bus-ctrlr mapping. Currently, the ctrlr structure is
empty, but with follow-on changes, new members will be added to this
structure as required.
BUG=None
