Two fixes for the EFI subsystem coming via the TPM tree as agreed by Heinrich

The LMB patch fixes a failure in SystemReady testing. Nothing bad happens
without the patch in the device operation, but the return values are wrong
and SCT tests fail for MemoryAllocationServicesTest category.

The second is a shielding the device against mistakes in the definition of
struct fields needed by the capsule update mechanism. Instead of crashing,
print a humna readable message of what's wrong.

Two changes from Heinrich.
One is adding some missing TPM files for proper maintenance.
The second addresses Coverity-ID: 356664 replacing a mempcy()
which has undefined behavior with memmove()

This PR contains various improvements in the A/B update logic for EFI

- Read both copies of metadata, in case one of the is corrupted
- Check the metadata version against the running firmware to make sure it's
  allowed
- Limit the use of a revert capsule if the board is on a trial state and
  make sure it's not applied if the max counter has expired

Back when the TPM subsystem was refactored tpm_tis_wait_init() ended up
being called after tpm_tis_init() which initializes values the former needs.

Since we added more TPM chipsets since then sitting on an i2c bus, this patch
folds in tpm_tis_wait_init into tpm_tis_init and makes sure it's called in the
right order regardless of the bus the TPM sits on.

When the EFI TCG measurement code moved from EFI to the TPM subsystem for
general use some prototypes changed from returning efi_status_t to int,
which is more appropriate for the non-EFI APIs. However, some of the
EFI callsites never changed and we ended up assigning the int value to
efi_status_t.

This is unlikely to cause any problems, apart from returning invalid
values on failures and violating the EFI spec.
