media: iris: don't specify min_acc_length in the source code

Browse Source 
The min_acc length can be calculated from the platform UBWC
configuration. Use the freshly introduced helper and calculate min_acc
length based on the platform UBWC configuration instead of specifying it
directly in the source.
