ice: fix missing priority callbacks for U.FL DPLL pins

The U.FL2 input pin advertises DPLL_PIN_CAPABILITIES_PRIORITY_CAN_CHANGE
in its capability mask, but ice_dpll_pin_ufl_ops does not provide
.prio_get and .prio_set callbacks. As a result the DPLL subsystem
cannot report or accept priority for U.FL pins: pin-get omits the prio
field on U.FL2 and pin-set with prio is rejected as invalid, even
though the capability is present. This prevents user space from using
priority to select or disable U.FL2 as a DPLL input source.

Reproducer with iproute2 (dpll command):

  # dpll pin show board-label U.FL2
  pin id 16:
    module-name ice
    board-label U.FL2
    type ext
    capabilities priority-can-change|state-can-change
    parent-device:
      id 0 direction input state selectable phase-offset 0
    /* note: no "prio" between "direction" and "state",
       even though priority-can-change is advertised */

  # dpll pin set id 16 parent-device 0 prio 5
  RTNETLINK answers: Operation not supported

After the fix the prio field is reported by pin show and pin set with
prio is accepted on U.FL2.

Add the missing .prio_get and .prio_set callbacks to
ice_dpll_pin_ufl_ops, reusing ice_dpll_sw_input_prio_{get,set}. The
same ops struct is shared by U.FL1 and U.FL2: U.FL2 (input) delegates
to the backing hardware input pin, while U.FL1 (output) does not
advertise DPLL_PIN_CAPABILITIES_PRIORITY_CAN_CHANGE so the dpll core
capability gate never invokes prio_set for it, and prio_get reports
the OUTPUT sentinel (ICE_DPLL_PIN_PRIO_OUTPUT) on the output side
exactly like the SMA path does today.
