ipq807x: delete unused legacy eMMC sysupgrade code

All ipq807x devices that were using the legacy 'mmc_do_upgrade' eMMC
sysupgrade code were ported to the replacement 'emmc_do_upgrade' code.

-# this can be used as a generic mmc upgrade script
-# just add a device entry in platform.sh, 
-# define "kernelname" and "rootfsname" and call mmc_do_upgrade
-# after the kernel and rootfs flash a loopdev (as overlay) is 
-# setup on top of the rootfs partition
-# for the proper function a padded rootfs image is needed, basically 
-# append "pad-to 64k" to the image definition
-# this is based on the ipq806x zyxel.sh mmc upgrade
