[PATCH 1/4] mips: n64: Use DEFINE_RES_*() helpers

[Thorsten Blum <blum@kernel.org>]

Use DEFINE_RES_MEM(), DEFINE_RES_IRQ(), and DEFINE_RES_MEM_NAMED() to
simplify resource initialization. Drop the now-unused linux/string.h
include.

Also use PLATFORM_DEVID_NONE instead of -1 for devices without an
instance ID.
