crypto: caam - make write transactions bufferable on PPC platforms
Previous change (see "Fixes" tag) to the MCFGR register clears AWCACHE[0]
(which is "1" at POR).
For PPC-based platforms, this makes all writes non-bufferable, causing
a performance drop.
Rework previous change such that MCFGR[AWCACHE] is set to:
-4'b0001 (default value at POR) for PPC-based platforms
-4'b0011 (default value at POR + AWCACHE[1]) for ARM-based platforms
