Remove MMU hacks

Unicorn has included some ugly hacks to provide a envirement where vaddr == paddr.
These hacks where to use the full 64 bit mappings on x86 without init the mmu
and some memory redirect for MIPS.

The UC_TLB_CPU mode defaults to vaddr == paddr, therfor these hacks aren't
required anymore.
