Create CPUDIR variable
The CPUDIR variable points to the location of a target's CPU directory. Currently, it is set to cpu/$CPU. However, using $CPUDIR will allow for more flexibility in the future. It lays the groundwork for reorganizing U-Boot's directory structure to support a layout such as: arch/$ARCH/cpu/$CPU/* (architecture with multiple CPU types) arch/$ARCH/cpu/* (architecture with one CPU type) Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

peripherals around the core) is moved into
