MIPS: SEAD3: Implement OF support.

Activate USE_OF for SEAD-3 platform. Add basic DTS file and convert memory
detection and reservations to use OF.

[ralf@linux-mips.org: Remove unnecessary #ifdef wrapper in generic.h.  Make
<asm/mips-boards/generic.h> inclusion work even without prior
<linux/of_fdt.h> inclusion.]
