Conversion of Samsung pinctrl bindings to dtschema followed up with
alignment of DTS files to the dtschema.
The entire work consists of three parts but everything should be merged
at once to avoid dtschema check errors:
1. Samsung pinctrl driver change necessary to accept new DTS (driver
depends on node names and this has to be adjusted because of dtschema).
2. Conversion to dtschema which brings requirement of different naming
of the GPIO nodes.
3. DTS commits depending on driver (1) above, which convert all GPIO pin
bank names to new naming, required by dtschema.
This also includes few cleanups around DTS which are here to avoid
any merge conflicts.
The Samsung pinctrl driver changes are backwards compatible. However
the DTS changes (renaming nodes) could cause problems in out-of-tree or
other project implementations of the driver.

Exynos5260 bindings require to feed clock controllers with certain clock
inputs. The IO clocks are expected to be provided by the board. The
PHY clocks are usually followed by mux which can choose between the PHY
clock and main 24 MHz oscillator, so skip defining them and just use the
latter one.

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
and "Exynos" names.
"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names. Therefore they should be written with lowercase letters starting
with capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.
Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
https://www.samsung.com/semiconductor/privacy-global/).

Replace in DT sources hard-coded values for pinctrl configuration like pull

especially that some drive strengths values are quite non-obvious.

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:
"Node /memory has a reg or ranges property, but no unit name"
The disassembled DTB are almost the same besides an empty chosen
node being removed and nodes reordered, so it should not have
functional changes.

But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
