Revert "x86: create a non-zero sized bm_pte only when needed"
This reverts commit 698609bdcd35d0641f4c6622c83680ab1a6d67cb.
69860 breaks Xen booting, as it relies on head*.S to set up the fixmap
pagetables (as a side-effect of initializing the USB debug port).
Xen, however, does not boot via head*.S, and so the fixmap area is
not initialized.
The specific symptom of the crash is a fault in dmi_scan(), because
the pointer that early_ioremap returns is not actually present.
