binman: fit: Allow running fdtgrep on devicetree blobs
When using FIT to load firmware builds for multiple models, the FIT must
include a common binary along with a number of devicetree blobs, one for
each model. This is the same mechanism as is used for loading an OS.
However, SPL builds do not normally use the full devicetree, but instead
a cut-down version which various nodes and properties removed.
Add a new fit,fdt-phase property to allow binman to produce these
devicetree blobs.

binman: Add support for alternative FDTs
FIT provides a way to select between different devicetree blobs
depending on the model. This works fine for U-Boot proper and allows SPL
to select the correct blob for the current board at runtime. The boot
sequence (SPL->U-Boot proper) is therefore covered by the existing
feature set.
The first boot phase (typically TPL) cannot use FIT since SoC boot ROMs
don't currently support it. Therefore the TPL image must be specific to
each model it boots on.
To support booting on mulitple models, binman must therefore produce a
separate TPL image for each model, even if the images for the rest of
the phases are identical.
TPL needs to be packaged as an executable binary along with a reduced
devicetree. When multiple models are supported, a reduced devicetree
must be provided for each model.
U-Boot's build system is designed to build a single devicetree for SPL
builds, so does not support this requirement.
Add a new 'alternatives' feature to Binman, allowing it to automatically
subset a devicetree to produce the reduced devicetree for a particular
phase for each supported model. With this it is possible to produce a
separate TPL image for each of the models. The correct one can then be
loaded onto a board, along with the common FIT image(s).

binman: Write the compressed output to a file
When an entry is compressed, write the compressed contents to a file so
that it is possible to see what was produced. This aids debugging with
new images.

qconfig: Sort the boards by name when finding
There is no particular ordering of the board list at present, since it
is generated by a multi-threaded process. Sort them by name to make it
easier to see if a particular board is present.

buildman: Show board list with -x
When -x is used, buildman does not show the list of boards that will be
built, since there are no terms which cause boards to be added, only
terms which cause them to be removed.
Add a special case to fix this.

power: regulator: qcom-rpmh-regulator: port ops to U-Boot
Port over the regulator ops to U-Boot's regulator API. Add back the
pmic5 mode map using U-Boot dm_regulator_mode API and adjust the
pmic5_pldo and pmic5_pldo_lv definitions. No functional changes.
A lot of the features in here are only relevant when running
multi-threaded with interrupts. Drop everything except what we need to
run single-threaded with a single TCS (which is all the rpmh-rsc
framework in U-Boot supports).
Keep rpmh_write_async() for simplicity and make it wrap the regular
rpmh_write().
Minor adjustments to fix building with U-Boot and work correctly as a
synchronous driver without interrupts. RPMh is fast enough that we can
get away with just firing off requests and assuming they complete.
U-Boot behaviour changes are annotated with a "U-Boot:" comment.
soc: qcom: rpmh-rsc: drop unused multi-threading and non-active TCS support
Since U-Boot is single threaded, we can avoid most of the complexity
that comes with handling more than one in-flight TCS. Drop all the rpmh
code associated with multi-threading as we'll instead wait for a
response on each TCS.
Keep the header pointer in the .data section so we don't initialize it
again after relocation, adjust cmd_db_get_header() to work with the
U-Boot API, and skip validating the header since all cmd-db users are
children of the rpmh-rsc and those children will only probe if cmd-db
initializes successfully.
Qualcomm platforms may have drivers that bind to reserved memory nodes
(cmd-db [1] and smem [2]) which are relevant to U-Boot. Include
/reserved-memory in dm_extended_scan() so that these will be handled
correctly.
