The dragen2 and ucsimm/ucdimm files require a bit of
custom code compared to the other dragonball platforms,
move them into separate files as a preparation for a
build fix.

Just a small cleanup after I ran into some issue during build
testing my timer patches, the second patch contains the
actual bugfix but relies on this preparation patch.

2.27.0
Building a kernel with multiple dragonball based boards
enabled needlessly causes a link failure because of duplicate
config_BSP() functions between the CPU versions.
Avoid that merging the three almost identical files into one,
and hiding the CPU configuration behind the board config.
The pr_info() lines are consolidated in one place.
It is still not possible to run a kernel configured for
more than one board, but at least configurations that can
be selected can also be built now.
