ARM: Davinci: Fix DM644x timer overflow handling and cleanup
Fix ARM based DaVinci DM644x timer overflow handling and cleanup timer code.
Changes:
- Remove *_masked() functions as noted by Wolfgang
- Adapt register naming to recent TI spec (sprue26, March 2007)
- Fix reset_timer() handling
- As reported by Pieter [1] the overflow fix introduced a delay of factor 16 (e.g 2 seconds became 32). While the overflow fix is basically okay, it missed to divide udelay by 16, too. Fix this.

- Remove software division of timer count value (DIV(x) macro) and do it in hardware (TIM_CLK_DIV).
Many thanks to Troy Kisky <troy.kisky@boundarydevices.com> and Pieter Voorthuijsen <pieter.voorthuijsen@Prodrive.nl> for the hints & testing!
Patch is compile tested with davinci_dvevm & sonata & schmoogie configuration and tested by Pieter on DaVinci EVM hardware.
