binder: use freezable blocking calls

Avoid waking up every thread sleeping in a binder call during
suspend and resume by calling a freezable blocking call.  Previous
patches modified the freezer to avoid sending wakeups to threads
that are blocked in freezable blocking calls.

This call was selected to be converted to a freezable call because
it doesn't hold any locks or release any resources when interrupted
that might be needed by another freezing task or a kernel driver
during suspend, and is a common site where idle userspace tasks are
blocked.

msm_fb: display: change TE simulation and read pointer interrupt timing

The current parameters for command mode TE simulation on mdp side are
not straightforward and cause double read pointer interrupts. Now make
read pointer interrupt and line counter reset happen right at h/w
vsync, and kick_off start position and height are set to back porch
and max respectively, so timing is much simplified and the chance of
tearing is reduced.
