Add data cache support for arm1136 systems.
Enable "cache" command on Qong board and test performance.
Test 1: Loading 127 MB of data from NAND flash into RAM:
Instr. Cache off on on
Data Cache off off on
--------------------------------------------------
QONG (ARM11) 177s 95s 43s = x 4.1
Test 2: uncompressing a gzipped image from RAM to RAM
(size compressed: 6.5 MiB, uncompressed: 35 MiB):
Instr. Cache off on on
Data Cache off off on
--------------------------------------------------
QONG (ARM11) 1.54s 0.95s 0.18s = x 8.6
