Remove "struct of_compat_data" and replace its usage with
"struct device_compatible_entry"; they are ABI-compatible.

Fix several "loses const qualifier" bugs encountered during
this conversion.

Remove a build dependency on SOC_EXYNOS4 and SOC_EXYNOS5.  Now runtime.

exynos_bootstrap doesn't need an argument

Sync with HEAD

Resolve a couple of conflicts (result of the uimin/uimax changes)

Some changes to bring back exynos4 support and make exynos5 support more
modern/generic

- Provide a exynos_platform_early_putchar based on CONSADDR and remove
  EXYNOS_CONSOLE_EARLY
- Provide devmaps for exynos4 and exynos5
- Simplify exynos_bootstrap
- Update exynos_start.S to use exynos_platform_early_putchar - this
  needs a fix in a9_subr.S for arm_cpuinit to save lr in a callee save
  register and not use ip.  Maybe this change is safe now, but too much
  testing required to commit it now.

Sync with HEAD

Make the pinctrl driver actually work.

XU4 i2c, gpio & pinctrl changes

modify exynos_gpio.c to support the new pinctrl model.
set up the new pinctrl model in exynos_pinctrl.c

Flesh out exynos_i2c.c and set it up to use the new pinctrl model.  NOTE:
exynos_i2c.c is still incomplete.  I need to figure out what to set the
prescaler and scaler to.

XU4 GPIO Review Changes

Implement suggestions from Jared.

XU4 GPIO FDT broken snapshot

This is broken. exynos_gpio_bank_config and the call to it are wrong, and
the acquire function doesn't work.

But I'm in over my head and I need to discuss this:

There is a problem with the dtd: it doesn't have addresses for the individual
gpios.  Do I add the addresses to it, or go back to the old version where I
have them hard coded in the driver.

There is a problem with creating the gpio device entries:  I suspect I really
need to treat the pinctrl devices as busses and create the gpios as attached
to those busses, but I'm not familiar with how to do that in NetBSD. At the
minimum, a pointer to a similar situation would give me code to follow.
This is different than the usual bus attachment in that the gpios aren't
devices in the dtd (they don't have "compatible" properties) so they don't
get an attach routine called.  An alternative to generating the bus
attachments might be to add "compatible" properties to the GPIO entries
in the dtd. so that they do get attached in the normal way.

If I'm going to modify the DTD, then it should be checked in, so a decision
on where to check them in would be nice, even if it does mean spreading them
all over because of license issues.  (This DTD is GPL v2)

XU4 FDT -- fix bus tags

I got away with not having the generic bus tags for getting minimum fdt to
work; but for real drivers have to actually have them.  Make necessary
corrections.

EXYNOS Rewrite step 2 of N: New exynos_gpio.c

I can't bring  myself to fully nuke from orbit, so there are really two
things in this checkin:

1) A major rewrite of exynos_gpio.c, based mostly on the Nvidia
   tegra_gpio.c file.  This is missing a major function that will be
   added the first time a customer for it is integrated, which is meant to
   select pins based on aliases, rather than pin bank names.

2) A small number of changes to other files that keep the tree compiling
   and progressing as far as ever; except it is now 5422 specific and
   will not boot on the other exynos socs, which I don't have hardware to
   test.

The choice to remove functionality is always controversial, but since
we are doing a significant rewrite and I don't have either
documentation or hardware *and* none of the code really works now
anyway, I'm taking the stance that only tested functionality should be
added, and that we'll layer the other exynos socs on this once it
fully boots.
