These represent the two kinds of (incompatible) OMAP I2C
peripheral unit in use so far.
The constants are in linux/i2c-omap.h so the omap i2c driver can have
them too.

As part of removing cpu_...() from the OMAP I2C driver, we need to
convert the CPU tests into functionality flags that are set by
hwmod class in the same way the IP revision is.
More flags are needed than will fit in the existing u8 flags
member of omap_i2c_dev_attr.
These flags can refer to options inside the IP block but they are
most needed for information about cpu implementation specific
options that are not part of the IP block itself. For example,
how the CPU data bus is wired to the IP block databus differs
between OMAP cpus and affects how you must shift the address in
the IP block, but is not a feature of the IP block itself.

The commit b63128e812 broke the pin muxing
for I2C busses that are enabled from the kernel command line.
Fix this by defining the board registration function omap_register_i2c_bus
in common platform code as it was before but keep the muxing in architecture
dependent files.

Otherwise we cannot limit new mux code to mach-omap2.
The same signal names should eventually work for other
omaps under mach-omap2.
Note that these pins don't need to be OMAP_PIN_INPUT_PULLUP,
just OMAP_PIN_INPUT is enough.
