I just said in another email thread that we would need a CONFIG_DCR
option that DCR using drivers should depend on, if it ever happened
outside of powerpc.
Well, apparently this happened earlier than I expected.
Converting the driver to use the generic DCR interface
makes it possible to use in any system that provides this
interface, including those that use a hard CPU core with xilinx_fb
on an FPGA, so it makes sense to just change the dependency
in Kconfig and provide CONFIG_DCR in microblaze (unconditionally)
as well as in powerpc instead of the existing CONFIG_PPC_DCR.
