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.

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.
