21cf953a03 x86: disable zero mapping and add a boot pt for ap trampoline 
the application processor trampoline needs the trampoline physical
address to be mapped for the few instructions between loading the
page table and jumping to normal memory area; setup a new pt for them.

Also make it use its stack where it needs to be directly.

With that, x86 can finally remove the 0 page from its init mapping
