This patch adds IRQ support for the virtio GPIO driver. Note that this
uses the irq_bus_lock/unlock() callbacks, since those operations over
virtio may sleep. Also the notifications for the eventq are processed
using a work item to allow sleep-able operations.

This patch adds a new driver for Virtio based GPIO devices.

This allows a guest VM running Linux to access GPIO lines provided by
the host. It supports all basic operations, except interrupts for the
GPIO lines.

The MaverickCrunch support for ep93xx never made it into glibc and
was removed from gcc in its 4.8 release in 2012. It is now one of
the last parts of arch/arm/ that fails to build with the clang
integrated assembler, which is unlikely to ever want to support it.

The two alternatives are to force the use of binutils/gas when
building the crunch support, or to remove it entirely.

According to Hartley Sweeten:

 "Martin Guy did a lot of work trying to get the maverick crunch working
  but I was never able to successfully use it for anything. It "kind"
  of works but depending on the EP93xx silicon revision there are still
  a number of hardware bugs that either give imprecise or garbage results.

  I have no problem with removing the kernel support for the maverick
  crunch."

Unless someone else comes up with a good reason to keep it around,
remove it now. This touches mostly the ep93xx platform, but removes
a bit of code from ARM common ptrace and signal frame handling as well.

If there are remaining users of MaverickCrunch, they can use LTS
kernels for at least another five years before kernel support ends.

This rewrites the IXP4xx CF (IDE) libata driver to use the
device tree exclusively to look up its resources:

- Probe exclusively from the device tree and look up all
  resources from there.
- Allocate a local state container with devres and pass
  this around in .private_data.
- Initialize with struct ata_port_info.
- Use the .set_piomode() callback instead of the much
  wider .set_mode(), we only support PIO after all.
- Bump driver version number from 0.2 to 1.0 to reflect this
  wider change.
- Get a handle on the expansion bus syscon regmap to alter
  the timings on the chip select.
- Put in the more elaborate timing adjustment code for PIO0
  to PIO4 in 8 and 16bit mode from the downstream OpenWrt
  patch.

The board file initialization path and platform data include
is dropped because the board files will be deleted at the same
time as this patch is merged.

The platform data file is not deleted right now so as not to
conflict with the removal of board files.

This rewrites the IXP4xx watchdog driver as follows:

- Spawn the watchdog driver as a platform device from the timer
  driver. It's one device in the hardware, and the fact that
  Linux splits the handling into two different devices is
  a Linux pecularity, and thus it becomes a Linux pecularity
  to spawn a separate watchdog driver.

- Spawn the watchdog driver from the timer driver at probe().
  This is well after the timer driver as actually registered and
  started and we know the register base is available.

- Instead of looping back callbacks to the timer drivers for all
  watchdog calls, pass the register base to the watchdog driver
  and manage the registers there. The two drivers aren't even
  interested in the same register so the spinlock is totally
  surplus, delete it.

- Replace pretty much all of the content in the watchdog driver
  with a simple, modern watchdog driver utilizing the watchdog
  core instead of registering its own misc device and ioctl()
  handling.

- Drop module parameters as the same already exist in the
  watchdog core.

What remains is a slim elegant (IMO) watchdog driver using the
watchdog core, spawning from device tree or boardfile alike.

The Intel IXP4xx SoCs have an expansion bus that is usually just
used for flash memory and configured by the boot loaders and can
be accessed using the "simple-bus".

However some devices need more elaborate configuration and then we
need to provide a proper 3-unit address space indicating chip
select for each device and provide timing and similar information.
