Patch from Ben Dooks

Remove the include of bast-cpld.h, as it shouldn't be here as
it only defines some extra bast-specific registers, and does
not affect the configuration of the hardware dependenat items.
Ensure that the file is included in the one place it is needed
and not included.
This should discourage anyone else putting include files in
which do not affect the over-all hardware definitions.
