Commit 84badc5ec5fc ("ARM: dts: omap4: Move l4 child devices to probe
them with ti-sysc") moved some omap4 timers to probe with ti-sysc
interconnect target module. Turns out this broke pwm-omap-dmtimer
where we now try to reparent the clock to itself with the following:
omap_dm_timer_of_set_source: failed to set parent
With ti-sysc, we can now configure the clock sources in the dts
with assigned-clocks and assigned-clock-parents. So we should be able
to remove omap_dm_timer_of_set_source with clean-up patches later on.
But for now, let's just fix it first by checking if parent and fck
are the same and bail out of so.

This driver is no longer used as an early platform driver. Remove the
registration macro.

Invalid value silently disables use of the prescaler.
Use -1 explicitely for that purpose and error out on
invalid value.

As dmtimer no longer exports functions, make those previously
exported static (this requires few functions to be moved around
as their prototypes were deleted).

In the case of device tree boot the device platform data is usually
NULL so hook the platform data obtained from the match.
As part of un-constify the platform_data pointer.

Move the dmtimer driver out of plat-omap to clocksource.
So that non-omap devices also could use this.
No Code changes done to the driver file only renamed to timer-ti-dm.c.
Also removed the config dependencies for OMAP_DM_TIMER.
