kernel: use add_mtd_partitions() helper when using OpenWrt parsers

This helper uses hierarchical partitions layout following the way
upstream parsers work. It's closer to what we should use when mainlining
our solutions. It also doesn't require hacky casting of struct
mtd_partition to the const.

THIS WILL AFFECT KERNEL PRINTING PARTITIONS IN THE LOG

Something like:
[    3.930158] 0x0000004e0000-0x000001fb0000 : "rootfs_data"
will get replaced by:
[    3.907338] Creating 1 MTD partitions on "rootfs":
[    3.912142] 0x00000031d400-0x000001ded400 : "rootfs_data"

It's important to understand that "rootfs_data" in above example is a
*subpartition* of the "rootfs" now. To get absolute addresses (e.g. for
some debugging purposes) one has to add them to the "rootfs", e.g.
[    3.912548] 0x0000001c2c00-0x000001fb0000 : "rootfs"

(0x1c2c00 + 0x31d400 = 0x4e0000)
