qualcommax: ipq807x: fix sysupgrade for ZBT-Z800AX

Browse Source 
This router has two rootfs partitions and dualboot is used.
Vendor firmware may swap the rootfs partition location, u-boot append
'ubi.mtd=rootfs' in the end of cmdline. Since we use fixed-partitions,
force boot from the first rootfs partition to avoid boot failure.
