kernel: rewrite run_parsers_by_type() to use add_mtd_partitions()

Make run_parsers_by_type() more similar to the parse_mtd_partitions():
1. Use struct mtd_partitions
2. Use add_mtd_partitions()

This change simplifies run_parsers_by_type() by:
1. Dropping loop
2. Dropping code getting partition properties (name, offset, size)

Moreover this change allows passing more partitions details (e.g.
mask_flags).

One noticeable change introduced by this patch is adding parsed
partitions as children. This results in printing their *relative*
offsets which unifies this code with parse_mtd_partitions() behaviour.

Before:

[    1.804009] 0x0000004e0000-0x000000fb0000 : "rootfs_data"

After:
