Teach mx25l SPI flash driver to interact with fdt_slicer and geom_flashmap

The attached patch teaches the mx25l driver (sys/dev/flash/mx25l.c) to interact
with sys/dev/fdt/fdt_slicer.c and sys/geom/geom_flashmap.c.

This allows systems with SPI flash to benefit from the possibility to define
flash 'slices' via FDT, just the same way that it's currently possible for CFI
and NAND flashes.
