74xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache
The patch is following the commit 392438406041415fe64ab8748ec5ab5ad01d1cf7
mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache
This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.
lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.

also, the r2 is used as global data pointer.
