msm: mdss: extend PHY_RESET recovery to BTA_TIMEOUT case

In no panel connected case, when ESD is enabled we see
target is crashing because DSI controller is busy in waiting
for BTA from panel. This causes unwanted DSI PHY errors and
causes target crash due to watchdog bite.
This code change fixes the issue by extending the DSI PHY
recovery mechanism to BTA_TIMEOUT case also.
