Ladislav Michl 58a54f03e7 clocksource: timer-ti-dm: Check prescaler value
Invalid value silently disables use of the prescaler.
Use -1 explicitely for that purpose and error out on
invalid value.

Ladislav Michl 592ea6bd1f clocksource: timer-ti-dm: Make unexported functions static
As dmtimer no longer exports functions, make those previously
exported static (this requires few functions to be moved around
as their prototypes were deleted).

As part of un-constify the platform_data pointer.

Keerthy af04aa856e ARM: OMAP: Move dmtimer driver out of plat-omap to drivers under clocksource
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.
