VGV952CJW33-E-IR: Revert subpage handling in upgrade scripts.

The kernel handles these by itself since some time ago.

Revert "Use partition 'ubi' (mtd12) for rootfs and rootfs_data; use 512 UBI sub-blocks"

This reverts commit fabfbe6.

Revert "VGV952CJW33-E-IR: Sysupgrade: Deactivate subpages on nand."

This reverts commit ac64e9e.
