x86_32: always run the full set of paging state.

I am preparing to convert the boot time page table to the kernels
native format.  To achieve that I need to enable PAE. Enabling PSE
and the no execute bit would not hurt.  So this patch modifies
the boot cpu path to execute all of the kernels enable code
if and only if we have the proper bits set in mmu_cr4_features.
