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
