[PATCH 7/7] ir-rx51: Fix sparse warnings

[Timo Kokkonen <timo.t.kokkonen@xxxxxx>]

Add missing __user annotation to all of the user space memory
accesses. Otherwise sparse is complainign about address space
difference in types.

Also struct lirc_rx51_platform_driver is missing static keyword even
though it should have it.
