ENGR00229290 EPDC: MX6: Adjust number of LUTs for 5-bit waveform

When a 5-bit waveform is loaded, the maximum number of available
LUTs is 16. The LUT allocator must account for this.

Note that 5-bit waveform loading is currently not supported in the
driver. However, this fix makes sure the LUT allocator is correct
when 5-bit support is added.
