Just a small correction on the commit log

Up to now the EFI subsystem was left out of the main U-Boot init process. This has led to various hacks over the years, with the most notable one being sprinkling around the efi init call to various places such as U-Boot commands, the early boot code etc.

Since EFI has it's own Kconfig option and people can remove it, let's wire up the EFI init call on an event for EVT_MAIN_LOOP.

Please ignore this sentence, it's a leftover from previous experiments.

This will also get rid of ad-hoc code in the main event loop, which was trying to initialize the subsystem early and perform capsule updates.

TODO:

• The efi_tcg protocol implicitly initializes the TPM, as a result some of the tpm selftests will fail with the RFC. If everyone agrees that this is a good idea, I'll clean up the TPM hacks as well
• We still need to run capsule updates on the main_loop() code since in some cases (e.g sandbox) we need preboot commands.
• wider tests, I've only run QEMU for now
