driver: implement dev_platform_get_and_ioremap_resource
To simplify porting of Linux drivers that make use of this function, add
an implementation to barebox. This was so far not done, because AT91 has
I/O memory regions that conflict with the error pointers.
Therefore, we emit a warning if we run into such a conflict.
