of/mips: Add device tree support to MIPS Add the ability to enable CONFIG_OF on the MIPS architecture. Signed-off-by: Dezhong Diao <dediao@cisco.com> [grant.likely@secretlab.ca: cleared out obsolete hooks, removed ARCH_HAS_DEVTREE_MEM, remove __init tags from header file, removed debugfs support hunk] [ddaney@linux-mips.org: backed out over aggressive trimming of hooks] Acked-by: Ralf Baechle <ralf@linux-mips.org> Tested-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

of/mips: Cleanup some include directives/files. The __init directives should go on the definitions of things, not the declaration, also __init is meaningless for inline functions, so remove it from prom.h. This allows us to get rid of a useless #include, but most of the rest of them are useless too, so kill them as well. If of_i2c.c needs irq definitions, it should include linux/irq.h directly, not assume indirect inclusion via asm/prom.h.
