Heiko Stuebner d64420e816 arm64: dts: rockchip: bulk convert gpios to their constant counterparts 
Rockchip SoCs use 2 different numbering schemes. Where the gpio-
controllers just count 0-31 for their 32 gpios, the underlying
iomux controller splits these into 4 separate entities A-D.

Device-schematics always use these iomux-values to identify pins,
so to make mapping schematics to devicetree easier Andy Yan introduced
named constants for the pins but so far we only used them on new
additions.

Using a sed-script created by Emil Renner Berthing bulk-convert
the remaining raw gpio numbers into their descriptive counterparts
and also gets rid of the unhelpful RK_FUNC_x -> x and RK_GPIOx -> x
mappings:

* the schematic as long as those rails interact in some way with
* the AP. AKA:
* - Rails that only connect to the EC (or devices that the EC talks to)
* are not included.
* - Rails _are_ included if the rails go to the AP even if the AP
* doesn't currently care about them / they are always on. The idea
* here is that it makes it easier to map to the schematic or extend
* later.
*
* If two rails are substantially the same from the AP's point of
* view, though, we won't create a full fixed regulator. We'll just
* put the child rail as an alias of the parent rail. Sometimes rails
* look the same to the AP because one of these is true:
* - The EC controls the enable and the EC always enables a rail as
* long as the AP is running.
* - The rails are actually connected to each other by a jumper and
* the distinction is just there to add clarity/flexibility to the
* schematic.
