Add support for devices with separate "init" and "default" pinctrl states.

Don't assume pinctrl-0 is the default configuration.

branches: 1.8.4;
Consolidate FDT [find "names" index by string] logic.

Implement subroutines for parsing out some of the generic properties
specified in the pinctrl bindings, and adapt Meson, Rockchip, and
Allwinner pinctrl back-ends to use them.

Fix infinite loop like in fdtbus_get_string_index.

Use queue(3) API to manage lists. NFCI.

branches: 1.4.4; 1.4.6; 1.4.8;
Fix the pinctrl api to match the spec. A pinctrl config can have more
than one xref, and an xref may have specifier data associated with it.

branches: 1.3.8;
Memory leak, found by mootja; not tested, but obvious enough. By the way,
I guess we should be handling the return value of OF_getprop.

FDT pinctl - review from Jared

These changes reflect a redesign based on a preliminary review by Jared.
Instead of the acquire/release/set/get approach of the original, this uses
a much simpler, and cleaner register/set approach.

FDT pinctrl

Add a pinctrl bus to FDT. This works against exynos, but someone(tm) needs
to think about whether it is general enough or too specific to exynos.
