power: pmic: mtk-pwrap: drop PWRAP_SLV_CAP_DUALIO on mt6359

Drop the PWRAP_SLV_CAP_DUALIO flag from the mt6359 PMIC definition. The
mt6359p variant of the PMIC does support dual I/O.

Prior to this change, the driver would attempt to write to the
PWRAP_DEW_DIO_EN register, which was not defined, so would write
register 0 (DONE2).
