ENGR00215592 - EPDC fb: Fix bug in selecting next LUT when 0-31 busy
If LUT 63 is busy and LUTs 0-31 are busy, the epdc_choose_next_lut
function was not correctly selecting an available LUT between 32-62.
Instead, it was returning 0. This fixes that issue by properly
offsetting the available LUT from the second 32-bit segment of the
64-bit LUT field.
