ANDROID: vendor_hooks: Add vendor hooks for key combinationASB-2020-09-05_11-5.4
When some problems happened in android, we can't use adb command because
android can be abnormal state. And we can't use uart because
uart pin is not connected in the board. So we need key combination
functions for debugging.
This function should only use in development environment.
In the market, this will be disabled.

[ Added "#ifdef __GENKSYMS__" around the include <<trace/hooks/debug.h>
to prevent CRC errors due to visibility of struct trace_eval_map ]
