Add a config option to reset system soon after processing capsule update on disk. This is required in UEFI specification 2.9 Section 8.5.5 "Delivery of Capsules via file on Mass Storage device" as;
In all cases that a capsule is identified for processing the system is restarted after capsule processing is completed.This also reports the result of each capsule update so that the user can notice that the capsule update has been succeeded or not from console log.

Changes in v2:
- Remove kconfig option to disable this feature.
- Use panic() instead of do_reset() so that if the reset fails, the machine halt.
- Log the result of each capsule update always.

log_err()? log_info() is better, I think.

If CONFIG_PANIC_HANG is enabled, the system won't restart. It's not what we want here.
