Ps2KbdCtrller: Make wait for SUCCESS after BAT non-fatal
Recent model Chromebooks only return ACK, but not
BAT_SUCCESS, which causes hanging and failed ps2k init.
To mitigate this, make the absence of BAT_SUCCESS reply
non-fatal, and reduce the no-reply timeout from 4s to 1s.
Tested on google/dracia and purism/librem_14
