The Makefile of mach-sunxi used to build PRCM and RSB according to the
SoC's MACH_SUNxI macro, which makes it needed to add lines for new SoC
generation.

Change this behavior to invisible options in sunxi Kconfig, so that new
lines are not needed for new SoC. Also it allows more accurate control
of the build of the related sources, for example, V3s (sun8iw8) and R40
(sun8iw11) do not have PRCM at all, and H3 (sun8iw7) do not have RSB,
but these functions are built with the old code.
