powerpc: Remove stale declarations in mmu_decl.h

rtas_size and rtas_data are not used anymore since at least
commit 7c8c6b9776fb ("powerpc: Merge lmb.c and make MM initialization
use it.")

Remove them.

Since commit 4b74a35fc7e9 ("powerpc/32s: Make Hash var static")
the forward declaration of struct hash_pte is unneeded.

Remove it.

__initial_memory_limit_addr was removed by commit e63075a3c937 ("memblock:
Introduce default allocation limit and use it to replace explicit ones")

Remove the declaration.
