payload/tianocore: Fix patch to preserve coreboot table
Part of the original patch, commit 85a90e1, reverted edk2 commit:
1d7258f [CorebootModulePkg:Removing EFI_RESOURCE_ATTRIBUTE_TESTED]
which had the unintended effect of causing memory above 2GiB
from being unavailable (marked reserved) when booting without a
connected display (aka headles mode).
This commit strips the patch to only the component needed to fix
reading of the coreboot table low memory pointer.
TEST: boot 4GB google/panther without connected display, verify
memory above 2GB available via 'dmesg | grep BIOS-e820' and 'free -m'
