dt-bindings: mtd: partitions: support marking rootfs partition
Linux needs to know what to use as root device. On embedded devices with
flash the only common way to specify that is cmdline & root= parameter.
That solution works with U-Boot which is Linux & cmdline aware but isn't
available with all market bootloaders. Also that method is fragile:
1. Requires specific probing order on multi-flash devices
2. Uses hardcoded partitions indexes
A lot of devices use different partitioning methods. It may be
"fixed-partitions" or some dynamic partitioning (e.g. based on parts
table). For such cases allow "linux,rootfs" property to mark correct
flash partition.
