The variable "cmp_str" always leaves me wondering if it is the DT name
of the current board (yes) or DT name in the FIT config entry (no).
In preparation for expanding the functionality here, rename it to
something that obviously means "this is the DT name we are looking for".

This moves the validity checking and typecasts all to one place away
from the string comparison logic, and it detangles the compile-time
and runtime control flow.
The new helper will also be used by U-Boot proper in a future commit.

Instead of using an entirely separate matching algorithm, simply update
the name of the DT we want to match. Enabling this logic does not depend
on the FIT config name, only on the initial guess of the board name.
Importantly, the initial guess must be "sun50i-a64-pine64-plus", because
otherwise the logic would trigger when "sun50i-a64-pine64-lts" was
written to the SPL header.

There are two different publicly-released revisions of the PinePhone
hardware, versions 1.1 and 1.2; and they need different device trees.
Since some GPIO pins were rerouted, we can use that to distinguish
between them.

This overwrites the name loaded from the SPL image. It will be different
if there was previously no name provided, or if a more accurate name was
determined by the board variant selection logic. This means that the DT
name in the SPL header now always matches the DT appended to U-Boot.

Previously, fdtfile was always the value in CONFIG_DEFAULT_DEVICE_TREE.
This meant that, regardless of the DT chosen by SPL (either by changing
the header in the image or by the selection code at runtime), Linux
always used the default DT.
By using the name from the SPL header (which, because of the previous
commit, always matches the DT used by U-Boot proper), Linux also sees
the same board as U-Boot/SPL, even if the boot script later loads a DT
from disk.

Subject: [PATCH 7/8] arm64: dts: allwinner: Add initial support for Pine64
PinePhone
At the moment PinePhone comes in three slightly incompatible variants:
- 1.0: Early Developer Batch
- 1.1: Braveheart Batch
- 1.2: Initial Production version
This syncs the Pinephone DTs from Linux 5.8-rc1.
