[OpenWrt-Devel] [PATCH 1/2] ath79: fix mikrotik WAP G-5HacT2HnD mtd partitions

[Thibaut VARÈNE]

In RouterBOARD parlance there never was an "art" partition.
This partition has always been named 'hard_config' on ar71xx.

This partition contains more than just ART (Atheros Radio Test) data. It
includes the hardware description (product code, serial, board
identifier, name, hardware options, MAC address), as well as other bits
affecting the operation of RouterBoot.
To avoid confusion with regular ART data, this partition is renamed in
line with historical ar71xx and ramips nomenclature as 'hard_config'.

This commit fixes the previous support files and implements the nested
RouterBoot partition scheme as already used by ramips-based SPI-NOR
RouterBOARD DTSes, as previously reviewed and implemented in bbe2cf657c.
