[ Upstream commit a21d2cc2f9039023105bf9f9bf1acf324d5ebf9d ]
PWM0 on rk3588-tiger is connected to the BLT_CTRL pin of the Q7 connector meant as the name implies to control a backlight device.
Therefore set the correct M1 pinctrl variant for it. The M0 variant cannot ever be used because that pin is routed to a connector pin on the Q7 connector that is reserved for CAN use and the pin reachable by the M2 variant is reserved for the embedded MCU on the SoM.
