net: enetc: simplify enetc4_set_port_speed()
Since phylink may pass SPEED_UNKNOWN to mac_link_up, handle it
explicitly by defaulting to SPEED_10, then replace the switch statement
with a direct call to PCR_PSPEED_VAL(). Also update PCR_PSPEED_VAL() to
use FIELD_PREP() for proper field masking instead of an open-coded shift.
