mb/google/rex/var/screebo: Set `SAGV_POINTS_0_1_2` to avoid hang
Setting SaGvWpMask to SAGV_POINTS_0_1_2 in dev tree can effectively
avoid the idle hang issue, but it will affect the system power.
(Before root cause, this is a short term workaround to unblock function test.)
BUG=b:287170545
TEST=Able to idle for more than 5+ hours without any hang.
