Add __force here so that sparse doesn't complain about us playing

This variable isn't exported outside of this file so mark it

into clk-next
From Tero Kristo:
"This pull request contains the TI clock driver set to move the
clock implementations under clock driver. Some small portions of
the clock driver code still remain under mach-omap2 after this,
it should be decided whether this code is now obsolete and should
be deleted or should someone try to fix it."
Slight merge conflicts with determine_rate prototype changes.

This clock provider uses the consumer API, so include clk.h
explicitly.

With most of the clock code under clock driver already, the low-level
register access code, and the init code for the same, is no longer
needed outside the clock driver. Thus, these can be moved under clock
driver also.

We should avoid exporting data from drivers, instead use an API for
registering the clock low level operations.

This is no longer used outside clock driver, so move it under the driver
and remove the export for it from the global header file.

As most of the clock driver support code is going to be moved under
drivers/clk/ti, an API for setting / getting the SoC specific clock
features is needed. This patch provides this API and changes the
existing code to use it.

There is a case where NULL can be a valid return value for
ti_clk_get_reg_addr, specifically the case where both the provider index
and register offsets are zero. In this case, the current error checking
against a NULL pointer will fail. Thus, change the API to return a
ERR_PTR value in an error case, and change all the users of this API to
check against IS_ERR instead.

Previously, the TI clock driver initialized all the clocks hierarchically
under each separate clock provider node. Now, each clock that requires
IO access will instead check their parent node to find out which IO range
to use.
This patch allows the TI clock driver to use a few new features provided
by the generic of_clk_init, and also allows registration of clock nodes
outside the clock hierarchy (for example, any external clocks.)

ti_dt_clk_init_provider() can now be used to initialize the contents of
a single clock IP block. This parses all the clocks under the IP block
and calls the corresponding init function for them.
This patch also introduces a helper function for the TI clock drivers
to get register info from DT and append the master IP info to this.

Some devices require their clocks to be available with a specific
dev-id con-id mapping. With DT, the clocks can be found by default
only with their name, or alternatively through the device node of
the consumer. With drivers, that don't support DT fully yet, add
mechanism to register specific clock names.
