[PATCH v6 21/27] x86: efi: Show the system-table revision

Simon Glass sjg at chromium.org

Show the revision of this table as it can be important.

Also update the 'efi table' entry to show the actual address of the EFI
table rather than our table that points to it. This saves a step and the
intermediate table has nothing else in it.

Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v6:
- Fix Alo typo in commit message

Changes in v5:
- Fix grammar in commit message

Changes in v3:
- Add new patch to show the system-table revision
