We're removing struct clk from the clk provider API, so switch
this code to using the clk_hw based provider APIs.

This code is never called with a basic clock type, so the check
here is not doing anything useful and is blocking the removal of
__clk_get_flags(). Remove the check so we can delete the
__clk_get_flags() API.

Several exported TI clock driver features are no longer needed outside
the clock driver itself, thus move all of these to the driver private
header file. Also, update some of the driver files to actually include
this header.

This is no longer needed in platform directory, as the legacy clock data
is gone, so move it under TI clock driver. Some static functions are
renamed also.

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.

TI clk driver now routes some of the basic clocks through own
registration routine to allow autoidle support. This routine just
checks a couple of device node properties and adds autoidle support
if required, and just passes the registration forward to basic clocks.
