This patch modifies the amba bus detection logic in the kernel
to detect the AMBA devices using the calculated resource
size information rather than the hard coded 4K size.
It also calculates the resource size when request mem region
and release mem region.

AMBA device resources were being reported as:
10004000-10004fff : <BAD>
This is because dev_name() was returning NULL prior to device_register.
Ensure that the struct device is properly initialized, and the name is
set before adding it to the device tree.

This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.
Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

This is needed if we wish to change the size of the resource structures.

Many ARM drivers do not need to include asm/irq.h - remove this
unnecessary include from some ARM drivers.
