The kernel configuration for the i.MX21ADS board (imx_v4_v5_defconfig)
doesn't enable 32 bit flash support. But the i.MX21ADS specific code
adds a 32 bit flash device, resulting in a kernel that refuses to
boot.

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.

tegra_init_clock() is written to call tegra2_init_clocks(), which only
exists if Tegra20 support is enabled. This breaks the build of a
Tegra30-only kernel.
tegra_init_clock() isn't actually used any more; tegra20_init_early()
calls tegra2_init_clocks() directly. So, just delete this function.

Currently, the Tegra pinmux is initialized at different times when booting
with and without device tree:
Without device tree:
1) Pinmux and GPIO drivers are registered.
2) Pinmux is configured.
3) All other drivers are registered.
With device tree:
1) All drivers are registered and probed, including pinmux and GPIO.
2) Pinmux is configured.
This change modifies board-pinmux.c to detect pinmux and GPIO driver
registration using bus notifiers. This allows pinmux configuration to
happen immediately after the pinmux driver is probed, irrespective of
whether the pinmux driver is manually registered by board-pinmux.c, or
if it's instantiated during device tree parsing.
To support this with device tree, the pinmux init functions must be
called prior to instantiating devices from device tree, so that the
notifiers are set up before-hand.

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.

Pin group PTA does not support function RSVD3. However, the current
pinmux driver doesn't check this when setting RSVD functions, and ends
up writing 3 to the HW register. 3 is actually represented by function
GMI, so update the pinmux table to request that instead in order to
obtain the same register programming without requesting invalid
configurations.
