Chu Shu Chen 194d4e9ffd fix(touch_pad): modify touch pad read function and touch_pad_deinit
The touch pad read function taks too much time within spin lock waiting for the "done bit". (about 7.6ms as we tested)
So we try to use a mutex on the touch read function and any other functions might change the "done bit".
