The PCIe0 instance of the PCIe controller on J784S4 SoC supports up to 4
lanes. Additionally, all 4 lanes of PCIe0 can be utilized on J784S4-EVM
via SERDES1. Since SERDES1 is not being used by any peripheral apart
from PCIe0, use all 4 lanes of SERDES1 for PCIe0.

Currently PCIe1 is setup to use SERDES0 lanes 0 thru 3, and USB0 is

This overlap in lanes causes the following reset related lane splat:

Let's limit the PCIe1 SERDES0 lanes to 0 and 1 to avoid overlap here.

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.
