Subject: [PATCH v3 1/8] ARM: dts: s3c2410: use local header for pinctrl register values

The DTS uses hardware register values directly in pin controller pin
configuration.  These are not some IDs or other abstraction layer but
raw numbers used in the registers.

These numbers were previously put in the bindings header to avoid code
duplication and to provide some context meaning (name), but they do not
fit the purpose of bindings.  It is also quite confusing to use
constants prefixed with Exynos for other SoC, because there is actually
nothing here in common, except the actual value.

Store the constants in a header next to DTS and use them instead of
bindings.
