OMAP242x H4 board update

- fix for ES2 differences.
- switch to using the cfi_flash driver.
- fix SRAM build address.
- fix for GP device operation.
- unlock SRAM for GP devices.
- display more device information.
- fix potential deadlock in omap24xx_i2c driver.
- fix DLL load values to match dpllout*1 operation.
- fix 2nd chip select init for combo DDR device.
- add support for CFI Intel 28F256L18 on H4 board.
