ARM: davinci: fixes for cam_enc_4xx board

Browse Source 
- change CONFIG_ENV_RANGE to contain 2 nand erase blocks,
  one for bad block reserve.
- remove from the envvariable "img_writeramdisk" the
  ubifsmount command, as it is not needed.
- erase the hole mtd partition containing u-boot
- save environment variable "dvn_app_vers" and "dvn_boot_vers"
  only after installing the new image.

- arm, davinci: fix eldk-4.2 warnings for cam_enc_4xx board
