omap: mux: Add new style pin multiplexing data for 34xx
Add new style mux data for 34xx. This should also
work with 3630 easily by adding the processor subset
and ball data.
Note that this data is __initdata, and gets optimized
out except for the GPIO pins if CONFIG_OMAP_MUX
is not set.
Also note that this data uses omap3630 naming for
the SDMMC registers instead of 34xx naming with just
MMC.

omap: mux: Add new style pin multiplexing code for omap3
Initially only for 34xx. This code allows us to:
- Make the code more generic as the omap internal signal
names can stay the same across omap generations for some
devices
- Map mux registers to GPIO registers that is needed for
dynamic muxing of pins during off-idle
- Override bootloader mux values via kernel cmdline using
omap_mux=some.signa1=0x1234,some.signal2=0x1234
- View and set the mux registers via debugfs if
CONFIG_DEBUG_FS is enabled

After conversion to gpiolib there's still some GPIOs left, that get

on GPCR/GPDR registers), but otherwise unused. These GPIOs are mainly
sound related and should be configured by corresponding driver once
it is written.
Drop this initialisation and configure all GPIOs as input.
