snowball: android: mali: Add Streamline Support for Mali DDK

ARM's Streamline Performance Analyzer now supports Mali graphics.
This requires support from the Mali kernel module which this patch adds.

These changes were delivered by ARM Ltd in a patch file called:
r2p3-01rel0_gpl_driver_streamline_support.patch that came with a
README.txt which included the following...

BUILDING THE DRIVER

  The driver can be built as normal. Profiling instrumentation is
  enabled by default by the patch. To disable it, use

	USING_PROFILING=0

  in your build command. To revert to the old-style profiling code,
  use

	USING_INTERNAL_PROFILING=1

  this option will disable the Streamline profiling support.

KNOWN ISSUES

  * Attempting to read L2 cache counters when the hardware block is
    powered down could potentially lead to a hang due to a lack of
    locking. This will be addressed in a future driver update.
