U-Boot is moving to a new set of tags to indicate devices that
should be bound/probed in early bootstrap phases. Add 'bootph-all'
tags from the new bindings such that probing the serial port
early on in U-Boot continues to work and doesn't hang the system.

This is in preparation for the next commit to use "framebuffer" as
compatible string for the boot framebuffer. This is in line with a
proposed change for boot framebuffer handling on Nvidia Tegra SoCs.
It will allow removing simpledrm via
drm_aperture_remove_conflicting_framebuffers().

The main part of function will be used to add a reserved memory region
for the framebuffer from "/vram" instead of the carveout.

This is to fix
OverflowError: Python int too large to convert to C ssize_t
in case the upper bound of a range is 1<<64.

Add some minimal implementation of virtio peripherals. At the level
of on-target hypervisor code we implement the MMIO layout and
maintain virtqueues. Once a buffer is available, we break into the
host proxyclient to deal with it.
Specific device-classes of the virtio spec ought to be implemented in
the proxyclient. Here the one device implemented is 9P transport,
exporting the m1n1 source directory.

This includes mapping it to 12.3.0 for compat in both DCP and GPU.
Added for machines with replaced logic boards that trigger the 12.3
bootloop issue.
Also fix the 12.5/12.6 version arrays which were wrong.

dcp_txt is mapped on dart-dcp and dart-dcpext so check if its reserved
memory node already exist before adding it.

This avoids having duplicate calls for dcpext* on each mayor SoC
variant. Fixes setting firmware versions for dcpext on t8103 and t8112.

This fixes m1n1 stage2 version numbers (for .tar.gz downloads) as long
as the directory name is left intact, and also supports packagers
passing their own version number if needed.

This uses a similar algorithm to t600x, but with different constants and
exponents. The current limit also engages here, so add it, and add the
t600x one too (even though it is never hit).
