MIPS: SNI: Fix conflicting wrapper symbols for headers. If Open Firmware / Device Tree support is enabled on a SNI RM kernel both <asm/mipsprom.h> and <asm/prom.h> will be included into some .c files. Since both headers use the same wrapper symbol only the inclusion of the first file will have an effect but the 2nd file will be ignored resulting in a build error.

MIPS: prepare for user enabling of CONFIG_OF In preparation to allow users to enable DeviceTree without arch or machine selecting it, we need to fix build errors on MIPS. When CONFIG_OF is enabled, device_tree_init cannot be resolved. This is trivially fixed by using CONFIG_USE_OF instead of CONFIG_OF for prom.h.

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.
