media: ti-vpe: cal: Remove static const cal_regmap_config template

The global static const cal_regmap_config template is only used in a
single location, to initialize 3 fields of a local variable. Two of
those fields then get overwritten. Remove the template and set the last
remaining field manually. Simplify the code by hardcoding the field
values instead of calculating them for a variable that always has the
same value.
