MISRA rule 2.2 defines dead code as "operations which are executed but
removal of these operations has no effect on program behavior".
Variable initializations violate this rule if initialized value is not
used and replaced.
This patch fixes some of these reported violations.

Move the get_litter() functions out of the main hal init to its own

There are many miscellaneous HALs for various MM related functionality.
This patch aims to migrate all the remaining MM code from the <chip>/
mm_<chip>.[ch] files in HAL files under hal/.
Much of this is fairly straightforward copy/paste and updates to the
HAL init files.
The exception to that is the move of the left over gv11b MMU fault
handling code in mm_gv11b.c. Having both a hal/mm/mm/mm_gv11b.c and
a gv11b/mm_gv11b.c file causes tmake to choke so the gv11b/mm_gv11b.c
file was moved to gv11b/mmu_fault_gv11b.c. This will be cleaned up in
a subsequent patch.
