Subject: [PATCH -next] soc: mediatek: Make symbol 'mtk_mutex_driver' static

The sparse tool complains as follows:

drivers/soc/mediatek/mtk-mutex.c:464:24: warning:
 symbol 'mtk_mutex_driver' was not declared. Should it be static?

This symbol is not used outside of mtk-mutex.c, so this
commit marks it static.
