Revert "ANDROID: Add vendor hooks for binder perf tuning"

Browse Source 
This reverts commit 17fff41db8.

The alloc->mutex to spinlock_t patches from [1] are being backported
into this branch. The vendor hooks will be reapplied on top of these
backports in a way that matches the new structure of the code.
