OMAP24xx I2C: Add support for set-speed

Browse Source 
Adds support for set-speed on the OMAP24xx I2C Adapter.

Changes to omap24_i2c_write(...) for polling ARDY Bit from IRQ-Status.
Otherwise on a subsequent call the transfer of last byte from the
predecessor is aborted and therefore lost. For exmaple when
i2c_write(...) is followed by a i2c_setspeed(...) (which has to
deactivate and activate master for changing psc,...).

Minor cosmetical changes.
