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.

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.

MIPS: Add helper function to allow platforms to point at a DTB. Add __dt_setup_arch() that can be called to load a builtin DT. Additionally we add a macro to allow loading a specific symbol from the __dtb_* section.
