MDSS and GPU drivers use different approaches to get min_acc length.
Add helper function that can be used by all the drivers.

Why not have this function return either 64 if the above is true or 32
if not, then rename to qcom_ubwc_min_acc_length() ?
You could imagine some function SoC having a 128b length for argument's
sake, it would make more sense just to modify this function then instead
of all of the callsites.
