ANDROID: vendor hooks: Add new android_rvh for adjust water mark

Browse Source 
The trace_android_vh_alloc_pages_adjust_wmark() and
trace_android_vh_alloc_pages_reset_wmark() have been deprecated,
because they cannot be used in a CPU offline or non-atomic context,
the trace_android_rvh_alloc_pages_adjust_wmark() and
trace_android_rvh_alloc_pages_reset_wmark() should be used instead.
