arm, arm926ejs: Flush the data cache before disabling it

The current implementation invalidates the data cache before turning it
off and causes problems on the hawkboard. See the discussion in
http://lists.denx.de/pipermail/u-boot/2012-January/115212.html

According to the ARM926EJ-S Technical Reference Manual, the cache should
be flushed instead.

Also fix the comments to match code.
