techpack: camera: add recovery mechanism to enforce fw update
If the firmware is broken or in unexpected status due to
the power drop or other reason, it will make the module breakage.
To reduce the firmware update failure risk, add recovery mechanism
that can enforce FW update again after reboot.
Bug: 157103802
Test: build pass, recovery mechanism is workable.
