If we call efi_clear_os_indications() before initializing the memory store
for UEFI variables a NULL pointer dereference occurs.
The error was observed on the sandbox with:
usb start
host bind 0 sandbox.img
load host 0:1 $kernel_addr_r helloworld.efi
bootefi $kernel_addr_r
Here efi_resister_disk() failed due to an error in the BTRFS implementation.
Move the logic to clear EFI_OS_INDICATIONS_FILE_CAPSULE_DELIVERY_SUPPORTED
to the rest of the capsule code.
If CONFIG_EFI_IGNORE_OSINDICATIONS=y, we should still clear the flag.
If OsIndications does not exist, we should not create it as it is owned by
the operating system.

If we look at the path that bootm/booti take when preparing to boot the
OS, we see that as part of (or prior to calling do_bootm_states,
explicitly) the process, bootm_disable_interrupts() is called prior to
announce_and_cleanup() which is where udc_disconnect() /
board_quiesce_devices() / dm_remove_devices_flags() are called from. In
the EFI path, these are called afterwards. In efi_exit_boot_services()
however we have been calling bootm_disable_interrupts() after the above
functions, as part of ensuring that we disable interrupts as required
by the spec. However, bootm_disable_interrupts() is also where we go
and call usb_stop(). While this has been fine before, on the TI J721E
platform this leads us to an exception. This exception seems likely to
be the case that we're trying to stop devices that we have already
disabled clocks for. The most direct way to handle this particular
problem is to make EFI behave like the do_bootm_states() process and
ensure we call bootm_disable_interrupts() prior to ending up in
usb_stop().

As described in the TCG spec [1] in sections 7.1.1 and 7.1.2 the FinalEvent
table should include events after GetEventLog has been called. This
currently works for us as long as the kernel is the only EFI application
calling that. Specifically we only implement what's described in 7.1.1.
So refactor the code a bit and support EFI application(s) calling
GetEventLog. Events will now be logged in both the EventLog and FinalEvent
table as long as ExitBootServices haven't been invoked.

UEFI it immediately changes back to 32-bit before starting U-Boot.
In order to support a 64-bit U-Boot app, update the Kconfig to add an
option for 32/64 bit. Update the prompt for the existing option so it is
clear it relates to the stub. Move both up to just under the choice that
controls them, since this looks better and the menu.
Use CONFIG_EFI_APP in the Makefile instead of CONFIG_TARGET_EFI_APP,
