ice: dpll: fix check for dpll input priority range

Supported priority value for input pins may differ with regard of NIC
firmware version. E810T NICs with 3.20/4.00 FW versions would accept
priority range 0-31, where firmware 4.10+ would support the range 0-9
and extra value of 255.
Remove the in-range check as the driver has no information on supported
values from the running firmware, let firmware decide if given value is
correct and return extack error if the value is not supported.
