MIPS: GIC: Move GIC_LOCAL_INT_* to asm/mips-gic.h

Move the definition of VP-local interrupts provided by the MIPS Global
Interrupt Controller to the new asm/mips-gic.h header to be alongside
the new accessor functions. Whilst at it, convert to an enum which lends
itself more easily to expansion & documentation.
