Convert the OMAP2+ clock code and data to rely on the common

clock framework for internal bookkeeping and the driver API.
 
 Basic test logs for this branch on top of Tony's cleanup-prcm branch
 at commit c9d501e5cb are here:
 
 http://www.pwsan.com/omap/testlogs/common_clk_devel_3.8_rebase/20121112192516/
 
 However, cleanup-prcm at c9d501e5 does not include some fixes
 that are needed for a successful test.  With several reverts,
 fixes, and workarounds applied, the following test logs were
 obtained:
 
 http://www.pwsan.com/omap/testlogs/TEST_common_clk_devel_3.8_rebase/20121112192300/
 
 which indicate that the series tests cleanly.
 
 N.B. The common clock data addition patches result in many
 checkpatch warnings of the form "WARNING: static const char *
 array should probably be static const char * const".  However, it
 appears that resolving these would require changes to the CCF
 itself.  So the resolution of these warnings is being postponed
 until that can be coordinated.
 
 These patches result in a ~55KiB increase in runtime kernel memory
 usage when booting omap2plus_defconfig kernels.

Merge tag 'omap-cleanup-c-for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8/clock

Convert the OMAP2+ clock code and data to rely on the common
clock framework for internal bookkeeping and the driver API.

Basic test logs for this branch on top of Tony's cleanup-prcm branch
at commit c9d501e5cb are here:

http://www.pwsan.com/omap/testlogs/common_clk_devel_3.8_rebase/20121112192516/

However, cleanup-prcm at c9d501e5 does not include some fixes
that are needed for a successful test.  With several reverts,
fixes, and workarounds applied, the following test logs were
obtained:

http://www.pwsan.com/omap/testlogs/TEST_common_clk_devel_3.8_rebase/20121112192300/

which indicate that the series tests cleanly.

N.B. The common clock data addition patches result in many
checkpatch warnings of the form "WARNING: static const char *
array should probably be static const char * const".  However, it
appears that resolving these would require changes to the CCF
itself.  So the resolution of these warnings is being postponed
until that can be coordinated.

These patches result in a ~55KiB increase in runtime kernel memory
usage when booting omap2plus_defconfig kernels.
