ARM: AM33xx: Add i2c support for AM33xx ...

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>.

drivers/base: fix corrupt device tree ...

dev_add_child is a very unsafe function. If called multiple times
it allows setting the same device to different parents thus corrupting
the siblings list. This happens regularly since:

|    bus: add bus device
|
|    automatically add it as parent of any bus device if none already specified
|
|    we have now a nice output per bus

If for example a FATfs is mounted this nice output per bus often ends with:

This patch fixes this by adding a device to its parents children list in
register_device so that dev_add_child is no longer needed. This function
is removed from the tree. Now callers of register_device have to clearly
set the parent *before* registering a device.
