On x86 platforms the SPI flash can be mapped into memory so that the contents can be read with normal memory accesses.
Add a new SPI method to find the location of the SPI flash in memory. This differs from the existing device-tree "memory-map" mechanism in that the location can be discovered at run-time.

Changes in v3:
- Move the get_mmap() method from the SPI_FLASH to the SPI uclass
Changes in v2: None
