xtensa: clean up WSR*/RSR*/get_sr/set_sr
WSR and RSR are too generic and collide with other macro definitions in the kernel causing warnings in allmodconfig builds. Drop WSR and RSR macros and WSR_* and RSR_* variants. Change get_sr and set_sr to xtensa_get_sr and xtensa_set_sr. Fix up users. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
