This causes a build error with CONFIG_WALNUT because kb_cs and kb_data
were removed in commit 917f0af9e5a9 ("powerpc: Remove arch/ppc and
include/asm-ppc").

Presumably since nobody has noticed this for the last 12 years, there is
not anyone actually trying to use this driver so we can just remove this
special walnut code and use the generic header so it builds for all
configurations.
