rockchip: use alternative CID path
Use an alternative path to access the CID of the SD card in MMC0, used for the generation of MAC addresses. With Kernel 5.10, the device name of the MMC controller changed, breaking MAC address generation. The new path is compatible with Kernel 5.4 as well as Kernel 5.10.
