pinctrl: npcm8xx: enable RMII outputs from RMII groups

Browse source

NPCM8xx uses GCR_INTCR4 bits to release the R1, R2 and RMII3
transmit outputs from Hi-Z.

Those bits need to follow the mandatory r1, r2 and rmii3 pin
groups. The R1_OEn, R2_OEn and R3_OEn side groups are optional and
should not be required just to enable RMII transmit outputs.

Program the INTCR4 bits when the corresponding RMII groups are
selected and clear them again when those pins switch back to GPIO or
another shared function.
