From: Heiko Stuebner <heiko.stuebner at cherry.de>

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.
