[PATCH-V2 0/4] ARM: OMAP2+: am33xx: Add clocktree and hwmod data

This patch adds complete clockctree and hwmod data for the
AM33XX family of devices.

This patch-series is cleaned up further from Paul's cleanup
activity on AM33xx clocktree, where all leaf nodes have been
removed and now modules enable/disable is controlled only
using hwmod framework interface.

There are certain modules, like clkdiv32k, debugss, etc..., for
which we still doesn't have hwmod_data present, so in order to
disable these modules during boot time, we still have to maintain
clk node for them. Comment has been added to highlight this, and
in the future we will cleanup this.
As far as, CLKDIV32K module, in reality is not module but still
we have MODULEMODE to control it, so we may have to keep this node
alone in the clocktree.

This patch is created on top of recently submitted patches
(accepted on the list) for am33xx voltage/powerdomain/clockcomain

This patch has been boot tested on BeagleBone platform.

History:
========
ClockTree: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg67095.html
Hwmod: http://www.spinics.net/lists/linux-omap/msg69189.html

Changes from V1:
	- Removed all leaf nodes from clocktree, and migrated
	  hwmod data to use parent clock of module's funtional clock
	  as main_clk.
	- Rebased patches against Kevin's omap_hwmod cleanup patch-series,
	  where, cpu_is_xxx is no longer needed and platform specific
	  api's will be registered during init call itself.
