Update omap5912osk board support

  - Fix OMAP support that omap5912osk compiles in current source tree
  - Update with code from "http://omap.spectrumdigital.com/osk5912"
    to fix problems with DDR initialization
  - Fix timer setup
  - Use CFI flash driver and support complete 32MB of onboard flash
  - Add "print_cpuinfo()" and "checkboard()" functions to display
    CPU (with frequency) and Board infos
