of: fix sparse warnings in fdt, irq, reserved mem, and resolver code
sparse generates the following warnings in drivers/of/: ../drivers/of/fdt.c:63:36: warning: cast to restricted __be32 ../drivers/of/fdt.c:68:33: warning: cast to restricted __be32 ../drivers/of/irq.c:105:88: warning: incorrect type in initializer (different base types) ../drivers/of/irq.c:105:88: expected restricted __be32 ../drivers/of/irq.c:105:88: got int ../drivers/of/irq.c:526:35: warning: incorrect type in assignment (different modifiers) ../drivers/of/irq.c:526:35: expected int ( *const [usertype] irq_init_cb )( ... ) ../drivers/of/irq.c:526:35: got void const *const data ../drivers/of/of_reserved_mem.c:200:50: warning: incorrect type in initializer (different modifiers) ../drivers/of/of_reserved_mem.c:200:50: expected int ( *[usertype] initfn )( ... ) ../drivers/of/of_reserved_mem.c:200:50: got void const *const data ../drivers/of/resolver.c:95:42: warning: incorrect type in assignment (different base types) ../drivers/of/resolver.c:95:42: expected unsigned int [unsigned] [usertype] <noident> ../drivers/of/resolver.c:95:42: got restricted __be32 [usertype] <noident> All these are harmless type mismatches fixed by adjusting the types.
