arm: Tegra: Use ODMDATA from BCT in IRAM
Walk the BIT and BCT to find the ODMDATA word in the CustomerData field and put it into Scratch20 reg for use by kernel, etc. Built all Tegra builds OK; Booted on Seaboard and saw ODMDATA in PMC scratch20 was the same as the value in my burn-u-boot.sh file (0x300D8011). NOTE: All flash utilities will have to specify the odmdata (nvflash --odmdata n) on the command line or via a cfg file, or built in to their BCT.
