Remove MMU identity map setup
We have a few good reasons to leave MMU disabled at EL3:
* Translations defined by our static pages might alias with the kernel,
leading to mismatched memory attributes and all kinds of pains.
* For legacy reasons, boot-wrapper accesses are not cached at the
moment (SCTLR_EL3.C is unset)
* It feels cumbersome to enable the MMU for one small exclusive
operation.
* Removing the static page tables also frees 4k of memory, which is
quite welcome when loading a 32-bit kernel case, where we only have
12k of bootloader RAM to play with.
