Some modules may assume "asm/setup.h" already include all headers which
needed by itself. So need let "asm/setup.h" include "linux/types.h", the
related error:

Save some pointless copying of the kernel command line and just use
boot_command_line instead.

Also remove default_command_line as it is not referenced anywhere, and
the DT code already handles the default command line.

Some internal kernel symbols were referenced in the exported setup.h.
This splits out the internal bits from the exported uapi bits.
