Changes:
- Kernel patches updated for the 5.10.41 linux-renesas kernel, most
changes are for the upstream rename of the non-engineering sample H3
from r8a7795 to r8a77951.
- The kernel patches have been renamed to match git format-patch /
devtool naming conventions to be a bit more consistent and hopefully
simplify future updates.
- To maintain consistency with the other rcar3 boards, as part of the
kernel patch updates the reference hardware devicetree has been
renamed to r8a77951-agl-refhw, which does result in a user visible
change in the .dtb name.
- The upstreamed, then reverted upstream patch to arm-trusted-firmware
to disable FDT generation has been replaced with a simpler patch to
just put "renesas,unknown" in the compatible string instead of
panic-ing. This should be easier to carry forward.
- Documentation updated for new branch & tag.

Tweak the arm-trusted-firmware bbappend to build the extra 1rank
firmware when building standalone with MACHINE=agl-refhw-h3, and
also add an anonymous python snippet to disable the default
firmware configurations from the base recipe in that situation
as well, as they are not useful.

The AGL reference hardware which is numbered 100 or above has
16Gbit/1rank DRAM. If you use the reference hardware described above,
please flash the firmware with the suffix "-agl-refhw-4x2g-1rank".

The override for the FDT deletion patch needs to be rcar-gen3
instead of agl-refhw-h3 so it will work when building with
MACHINE=h3ulcb in the AGL build as well as when building
standalone.

Leverage the reworked extra_opl_ipt hook in the rcar3 BSP's
arm-trusted-firmware recipe as of BSP v4.7.0 to enable building the
reference hardware flavor of the firmware as an extra firmware
version when building with MACHINE=h3ulcb. This will then enable
working inside the AGL build which combines the reference hardware
support into its h3ulcb build to avoid needing an extra platform
build.
Support for building standalone with MACHINE=agl-refhw-h3 has been
retained for potential use outside of the full AGL build. The
firmware documentation has been reworked to document the build and
flashing procedure for both types of build.
Based on initial prototype by Vasyl Vavrychuk at:

To generate a-t-f binaries equivalent to what is built for the other
H3 based boards in the AGL build process, add the KVM enabling patch
that is added by meta-agl-bsp. It is still unclear if there is a
straightforward path to working the separate a-t-f build for the
reference hardware into the AGL h3ulcb build, so this duplication
seems like a necessary evil for now.

Changes include:
- The provided kernel patches have been reworked to not modify the
salvator-x(s) devicetree source, but to introduce new files for the
reference hardware instead. There is some possibility that the
reference hardware devicetree could be based off the the salvator-x
with some work and perhaps splitting of the salvator-x source, but
for now the aim is to avoid breaking the salvator-x(s) with the
reference hardware changes.
- The modifications to the r8a7795 pinctrl driver have been replaced
with a splitting of the USB interface OVC pins into their own pin
groups, which has previously been done for other older Renesas
hardware. This allows booting the reference hardware off of the
same kernel as other H3 boards, at the expense of minor devicetree
modifications for them (e.g. h3ulcb). There is likely some more
work required if this needs to be upstreamed, as the ulcb.dtsi
changes would mean that the pinctrl drivers for M3 would also need
the new pin groups.
- All changes for the ST asm330lhh driver addtion have been moved to
that patch to the kernel.
- A machine conf file has been added for "agl-refhw-h3", and the
firmware documentation updated to document how to set up a build of
the firmware using it. This is required due to the firmware options
from this layer's arm-trusted-firmware bbappend not being compatible
with other H3 boards (eMMC versus Hyperflash boot). A definition
of the COMPATIBLE_MACHINE variable has been added to that bbappend
to make sure that attempting to use it with another H3 machine will
trigger an error. In AGL, the bbappend will need to be masked out
with BBMASK for now.
- The top-level README file has been updated to reflect the expected
integration in AGL.

Initial check-in of the contents of the meta-refhw directory from
the AGL_Refhw_sample_software_20200512.tar.gz archive provided by
Panasonic as the initial BSP for the AGL reference hardware. The
only change from the files as provided is that unneeded execute
file permissions have been removed.
