Otherwise the muxname passed to the function will get truncated.
Based on an earlier patch by rockefeller.lin@innocomm.com.

Add data for 2430. Big thanks to Paul Walmsley <paul@pwsan.com>
for generating usable mux data out of TRMs.

Allow compiling in new mux code on all mach-omap2 systems

Only POP and SIP are known to exist for 2420, 2430 seems to only have
SIP package available.

Make the omap_mux_read and write available for board code,
and rename omap_mux_set_board_signals into omap_mux_write_array.
Also add the related prototypes and comments into mux.h.
In some cases we want to change the signals dynamically,
mostly for power management.
Note that we cannot use the signal names as they are set
__init to save memory.

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.

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
