rockchip64-6.13: rk3568-odroid-m1: add nodes for i2c/pwm/spi/uart overlays

Browse Source 
- we used to have a bare-dt for odroid-m1 that got removed as it landed upstream
- but mainline doesn't have the nodes we use for the overlays
- at least i2c3 (which is aliased to i2c0) and uart1 breaks without them
