The 'bootph-all' tag was added to the dt-schema to describe the various
nodes used during the different phases of bootup with DT. Add the
bootph-all tag to all nodes that are used during the early stages of
bootup by the bootloaders.
This includes the console UART along with the SD and eMMC nodes and its
required regulators for the 3v3 to 1v8 transition and the various nodes
for Ethernet booting.

Reserve 576MiB of CMA as global CMA pool starting after initial 1GiB of
DDR.
AM62ax has different multimedia components such as Camera, Display, H.264
VPU and JPEG Encoder which use CMA for buffer allocations.
The 12x 720x480 realtime VPU decode use-case requires 544MiB of CMA,
additional 32MiB is kept as buffer in case some other peripheral also
require it while VPU is running.
The reason to choose latter 1GiB is to not overlap with existing memory map
which is utilizing initial 1GiB for remoteproc firmwares as shared here
[1].
Also some drivers such as JPEG require 32bit addressing so not allocating
from higher DDR address.

Prepare for pinctrl-single yaml binding and unify pin group node names.
Let's standardize on pin group node naming ending in -pins. As we don't
necessarily have a SoC specific compatible property for pinctrl-single.
I'd rather not add a pattern match for pins somewhere in the name for all
the users.
Trying to add matches for pins-default will be futile as on the earlier
SoCs we've already seen names like pins-sleep, pins-idle, pins-off and so
on that would need to be matched.
And as the node is a pin group, let's prefer to use naming -pins rather
than -pin as more pins may need to be added to the pin group later on.
