disp: msm: sde: update autorefresh disable sequence

Autorefresh might be still in enabled state after
write_ptr reached to display height. This patch
checks the autorefresh status bit and keeps polling
the bit till autorefresh sequence is in enabled
state. It times out after 1 second if autorefresh
is still in enabled state.
