mkconfig: add support for SPL CPU
Add support for specifying a differnt CPU for main u-boot and SPL
u-boot builds. This is done by adding an optional SPL CPU after the
main CPU in boards.cfg as follows:
normal_cpu:spl_cpu
This this case CPU will be set to "normal_cpu" during the main u-boot
build and "spl_cpu" during the SPL build.
