Fan Chen bb99828dee mt8173: Fix long latency issue of mtcmos contorl 
We found sometimes mtcmos operation is too long in spm (>1ms),
so update a new version to fix it.
I verified with 5 hours power_LoadTest, every mtcmos control
can finish in 500us (average is 100~200us).

Vikram Kanigiri c3ec0b9ea4 Use unified bakery locks API in Mediatek port 
This patch update Mediatek port to use the `DEFINE_BAKERY_LOCK` macro instead of
specifying the exact data structure to use for a bakery lock and the input
linker section that it should be allocated to.
