powerpc/boot: Expose Kconfig symbols to wrapper
Currently the wrapper is built without including anything in
$(src)/include/, which means there are no CONFIG_ symbols defined.
This means the platform specific serial drivers were never enabled.
We now copy the definitions into the boot directory, so any C file can
now include autoconf.h to depend on configuration options.
Fixes: 866bfc75f40e ("powerpc: conditionally compile platform-specific serial drivers")
