configs: mt8183: android: set rootfs from partition name
Currently, the root=/dev/<myrootfs> is hard-coded in the Android kernel
commandline.
Each time we update the partition scheme, we must also change this
commandline option, which is error prone.
Inspect the partition table and provide the root=/dev/X argument
to the kernel instead of hard-coding it.
