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

With the legacy clock data gone, this is no longer needed under platform,
so move it under the clock driver itself. Remove the exported clock driver
APIs as well, as these are not needed outside clock driver anymore.

of_device_id is always used as const.
(See driver.of_match_table and open firmware functions)
__initdata updated to __initconst for
static const struct of_device_id ti_clkdm_match_table[]

I "forgot" to update the dtb and the kernel crashed:
|Unable to handle kernel NULL pointer dereference at virtual address 0000002e
|PC is at __clk_get_flags+0x4/0xc
|LR is at ti_dt_clockdomains_setup+0x70/0xe8
because I did not have the clock nodes. of_clk_get() returns an error
pointer which is not checked here.

Some OMAP clocks require knowledge about their parent clockdomain for
book keeping purposes. This patch creates a new DT binding for TI
clockdomains, which act as a collection of device clocks. Clockdomain
itself is rather misleading name for the hardware functionality, as at
least on OMAP4 / OMAP5 / DRA7 the clockdomains can be collections of either
clocks and/or IP blocks, thus idle-domain or such might be more appropriate.
For most cases on these SoCs, the kernel doesn't even need the information
and the mappings can be ignored.
