x86/boot/32: Convert the 32-bit pgtable setup code from assembly to C
The new Xen PVH entry point requires page tables to be setup by the
kernel since it is entered with paging disabled.
Pull the common code out of head_32.S so that mk_early_pgtbl_32() can be
invoked from both the new Xen entry point and the existing startup_32()
code.
Convert resulting common code to C.
