This doesn't work at present, merely printing an error when U-Boot is
selected as a payload. This is because it adds a file into the U-Boot

- NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT
- MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT

Update tianocore branch used with default UEFIPAYLOAD option to
mrchromebox/uefipayload_202107 (July 2021) branch. This branch is
rebased on edk2 upstream commit 12e34cd2f7900578ee83cb01b8f1696a7bb7511b
[OvmfPkg/Bhyve: clean up TPM_ENABLE remnants] vs tag edk2-stable202105.
The main changes are fixes for e820 table parsing and support to disable
"Above 4G decode", which is required to boot distros with bootloaders
that expect to be loaded into RAM below 4G. This fixes booting with
Qubes, ZorinOS, Proxmox, among others.
Additionally, several commits on top of upstream have been consolidated,
reworked, and/or reordered for readability and maintainability.

BOOTBOOT is a multi-platform, architecture agnostic boot protocol.
The protocol describes how to boot an ELF64 or PE32+ executable inside
an initial ram disk image into clean 64 bit mode. This version uses
libpayload to do that. Depending on the lib's configuration, initrd
can be in ROM as a cbfs file or a Flashmap partition; on disk a GPT
partition or a file on a FAT formatted ESP partition.

So using '--recursive' adds a dependency on being able to reach servers we do not
