Added device register functions and cpu_is_am33xx()
function.
Adapted the i2c-omap driver. AM335x has a lower
clock rate and the timeout of polling the isr function
had to be increased.
Based on a patch from Shravan Kumar <shravan.k@phytec.in>.

The bootsource functions are not specific to the first stage
bootloader. They may also be used for detecting the
bootsource to decide where to load the environment from.
Also clean up includes in board files.

Added i2c support for omap4. Tested on pcm049.
Driver based on linux kernel implementation.
Also added a shift to access 16-bit registers
to make support for OMAP730/850 possible.
If accessing a non existing slave the bus will go into arbitration mode.
It's unable to recover from it.
