Instead of reshuffling what functions in the pinmux paths should be
__init and thus could keep references to __initdata, let's just remove
the annotations for now -- the tables are moving to device tree in the
next version anyway and the whole subsystem is being wired up. We will
go back and re-annotate where appropriate once things settle down.

This moves the implementation of *_pinmux_init() into a single location.
The board-specific pinmux data is left in each board's own file. This
will allow future changes that set up the pinmux in a more complex
fashion to do so without duplicating that code in each board's pinmux
file.

Rather than modifying seaboard_pinmux[] using ventana_pinmux[], split
seaboard_pinmux[] into common_pinmux[] and seaboard_pinmux[], and then
actually apply common_pinmux[] always, followed by the appopriate one
of seaboard_pinmux[] or ventana_pinmux[].

Some of the entries in ventana_pinmux[] are identical to what's already in
seaboard_pinmux[]. Remove the overrides from the Ventana table.

Seaboard and Ventana share some GPIOs, but others are different. Split the
GPIO table into common, seaboard-specific, and ventana-specific tables, so
that only the correct ones are enabled for each board. Add a few missing
audio-related GPIOs for Ventana.

*_pinmux_init() register the GPIO and pinmux devices so that they're ready
before any other device needs them.
*_pinmux_init() are also called by board-dt.c in order to set up the GPIO
and pinmux configurations. In this case, if we register the devices, they
end up being probed once due to this registration, and a second time due
to a device-tree node (or vice-versa). The second probe fails since the
memory regions are already requested. Besides, we don't actually want the
duplicated devices.
To avoid this duplicate registration, modify *_pinmux_init() to check
whether it's running on a DT machine. If not, register the pinmux devices.
If so, don't register them.
Finally, modify board-dt.c to call the *_pinmux_init() after all devices have
been instantiated from device-tree. This allows the GPIO and pinmux devices
to be instantiated and initialized before calling functions to configure the
hardware.
This has one disadvantage: The pinmux and GPIO initialization now happens
after /all/ devices are instantiated, rather than after just gpio and
pinmux but before anything else. So the correct HW configuration is not
in place when e.g. the SD/MMC device is probed. Long-term, this should be
solved by doing both:
a) Initializing the HW state from DT nodes during GPIO and pinmux device
probe.
b) Using the deferred driver probe mechanism, so that drivers can defer
their probe until after the gpio and pinmux drivers have probed.
v2: s/int is_dt/bool is_dt/
v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing
an explicit parameter into the function from outside.

The Tegra GPIO driver will be converted from static registration via
postcore_initcall() to be a platform device later in this patch series.
A new Tegra pinmux platform device will also be added.
Prepare for this by modifying all boards to register the appropriate
platform devices before-hand, so that when the drivers are converted,
those devices will be probed, and git bisectability will be maintained.

Seaboard has a couple of external USB ports. Add the platform devices and
GPIO infra-structure to enable these.
I tested both ports with a mouse on Seaboard non-clamshell.
This change is extracted from code in the ChromeOS 2.6.38 kernel.
