H. Peter Anvin fa76dab935 x86: clean up setup.h and the boot code
Make <asm/setup.h> usable by the boot code.

Clean up vestiges of the old command-line protocol from setup.h and
head_32.S (it is still supported from the boot loader point of
view, since it is converted to the new command-line protocol by the
boot code.)
