dm: use list_count_nodes() for counting list nodes
The linux kernel has the list_count_nodes() API functions which is
used for counting nodes of a list. This has now been imported in
U-Boot as part of an earlier commit. Use this function and drop the
list_count_items().

efi_memory: avoid possible null pointer dereference
Populate the previous memory descriptor node pointer only after it's
parent struct has been initialised. The compiler fixes this logic to
do the right thing, but it is better to have correct code in place.

efi_loader: adjust config options for capsule updates
EFI_IGNORE_OSINDICATIONS is used to ignore OsIndications if setvariable
at runtime is not supported and allow the platform to perform capsule
updates on disk. With the recent changes boards can conditionally enable
setvariable at runtime using EFI_RT_VOLATILE_STORE.
Let's make that visible in our Kconfigs and enable EFI_IGNORE_OSINDICATIONS
when set variable at runtime is disabled.
Since EFI_RT_VOLATILE_STORE needs help from the OS to persist the
variables, allow users to ignore OsIndications even if setvariable at
runtime is enabled.

v2 changes:
* Drop sw_blink_state structure, move its necessary fields to
led_uc_plat structure.
* Add cyclic_info pointer to led_uc_plat structure. This
simplify code a lot.
* Remove cyclic function search logic. Not needed anymore.
* Fix blinking period. It was twice large.
* Other cleanups.
v3 changes:
* Adapt code to recent cyclic function changes
* Move software blinking functions to separate file
* Other small changes
v4 changes:
* Refactoring of led_set_period() function
v5 changes
* Fix compilation if CONFIG_LED_BLINK is not defined
v6 changes:
* Enable LEDST_BLINK state unconditionally.
* Function led_set_period() becomes available when CONFIG_LED_BLINK
is disabled. This makes led code simpler.
* Software blinking requires about 100 bytes of data for a led. It's
not a good idea to allocate so much memory for each supported led.
Change the code to allocate blinking data only for required leds.
If hardware (or driver) doesn't support leds blinking, it's
now possible to use software implementation of blinking instead.
This relies on cyclic functions.

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).
