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. [1] http://article.gmane.org/gmane.comp.boot-loaders.u-boot/38179 - 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.
