display5: config: Add GPT verification and restoration code on SWUpdate entry

If GPT gets broken, then after N boot attempts we will run the SWUpdate
restoration image.
On its enter we will check GPT and restore it if needed.

To test it:
display5 > mmc write 0x12000000 4 8

It will overwrite the primary GPT table.
