commit a34cd9dfd03fa9ec380405969f1d638bc63b8d63 upstream.
R-Car Gen3 Hardware Manual Errata for Rev. 2.00 of October 24, 2019 changed the configuration bits for drive and bias control for the DU_DOTCLKIN3 pin on R-Car M3-N, to match the same pin on R-Car H3. Update the driver to reflect this.
After this, the handling of drive and bias control for the various DU_DOTCLKINx pins is consistent across all of the R-Car H3, M3-W, M3-W+, and M3-N SoCs.
