spi: Add support for memory-mapped flash

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.
