Sumit Semwal 872462cdfc OMAP2PLUS: clocks: Align DSS clock names and roles 
Currently, clock database has <dev, clock-name> tuples for DSS2. Because of
this, the clock names are different across different OMAP platforms.

This patch aligns the DSS2 clock names and roles across OMAP 2420, 2430, 3xxx,
44xx platforms in the clock databases, hwmod databases for opt-clocks, and DSS
clock handling.

This ensures that clk_get/put/enable/disable APIs in DSS can use uniform role
names.

* 2420 clock tree.

* NOTE:In many cases here we are assigning a 'default' parent. In many
* cases the parent is selectable. The get/set parent calls will also
* switch sources.
*
* Many some clocks say always_enabled, but they can be auto idled for
* power savings. They will always be available upon clock request.
*
* Several sources are given initial rates which may be wrong, this will
* be fixed up in the init func.
*
* Things are broadly separated below by clock domains. It is
* noteworthy that most periferals have dependencies on multiple clock
* domains. Many get their interface clocks from the L4 domain, but get
* functional clocks from fixed sources or other core domain derived
* clocks.
