msm: mdss: adv: fail ADV7533 probe if check revision fails

In current implementation we are ignoring check revision
failure for ADV7533 probe which might be because the chip
itself is not connected to platform. Due to this we are not
disabling the power supply even though chip is not connected
and going ahead causing power leakage. This change fixes the
same.
