This patch removes the call of the cpu_is_* functions completely
and uses id_tables instead.

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>.

cpu_is_omap2430() is set when CONFIG_ARCH_OMAP is enabled.
This fits for all OMAP/AM33xx boards supported in barebox.
Cleaned up all conditions that use the cpu_is_omap2430().
Also removed some unused defines.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

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.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.
