ipq40xx: rt-ac58u: replace ubi auto load hack
This patch replaces the custom autoload quirk of the RT-AC58U with a bootargs-append overwrite. The vendor's u-boot doesn't leave the bootargs / cmdline alone, so the it can't be overwritten in any other way right now... And of course, this will be a lot of fun to deal with once the device switches to the new spi-nand subsystem. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

-Subject: [PATCH 16/38] mtd: ubi: add auto_attach HACK for the ASUS RT-AC58U
-
-This patch adds a hack that allows UBI's autoattach feature
-to work with the custom ASUS UBI_DEV partition name.
-
-This is necessary because the vendor's u-boot doesn't leave
-the bootargs / cmdline alone, so the it can't be overwritten
-easily otherwise.
