Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.
For instances using of_node_cmp, this has the side effect of now using
case sensitive comparisons. This should not matter for any FDT based
system which all of these are.

The new clkctrl data layout for dra7xx is split based on clockdomain
boundaries. Previously the split was based on CM boundaries. This patch
adds the new data as separate data entity, retaining the compatibility
data also for now. The compatibility data can be removed once no longer
needed.

The change in the DTS data node naming prevents using underscore
within the node names and force usage of dash instead. On the other
hand, clockdomains use underscore instead of dash, so this must be
replaced within the driver code so that the mapping between the two
can be done properly.

Currently, only one clkctrl node can be added under a specific CM node
due to limitation with the implementation. Modify the code to pick-up
clockdomain name from the clkctrl node instead of CM node if provided.
Also, add a new flag to the TI clock driver so that both modes can
be supported simultaneously.

In certain cases it is possible that the timekeeping has been suspended
already when attempting to disable/enable a clkctrl clock. This will
happen at least on am43xx platform when attempting to enable / disable
the clockevent source itself, burping out a warning from timekeeping core.
The sequence of events leading to this:
-> timekeeping_suspend()
-> clockevents_suspend()
-> omap_clkevt_idle()
-> omap_hwmod_idle()
-> _omap4_clkctrl_clk_disable()
-> _omap4_is_timeout()
Avoid the issue by checking if the timekeeping is suspended and using
the fallback udelay approach for checking timeouts.

Previously, hwmod core has been used for controlling the hwmod level
clocks directly. This has certain drawbacks, like being unable to share
the clocks for multiple users, missing usecounting and generally being
totally incompatible with the common clock framework.
This patch adds support for clkctrl clocks for addressing the above
issues. These support the modulemode handling, which will replace the
direct hwmod clkctrl linkage. Any optional clocks are also supported,
gate, mux and divider.
