[PATCH v4 4/7] pinctrl: renesas: rzg2l: Update OEN pin validation to use exact match

[Biju]

From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>

The RZ/G2L SoC uses pin 0 from a port for OEN while RZ/G3L uses pin 1. The
existing greater-than comparison against oen_max_pin in
rzg2l_pin_to_oen_bit() would incorrectly accept any pin below that value
rather than enforcing the single valid OEN pin for each SoC. Replace the
range check with an exact equality test so that only the designated OEN
pin is accepted.
