arm, davinci: cam_enc_4xx board updates

- CONFIG_SYS_MMC_ENV_DEV, needed if environment on mmc
- wait for 1 second timer in board_late_init() only, if
  timer is running.
- add UBI/UBIFS support
- add FIT images support
- menu support
- U-Boot max size now 0xa0000
- SPL now Block 0 page 0
- new MTD partitioning
  0x00000000 SPL
  0x00020000 UBL-Header
  0x00040000 UBL-Header
  0x00060000 UBL-Header
  0x00080000 UBoot (0xa0000(U-Boot length) + 0x60000(3 spare blocks))
  0x00180000 ENV- Variablen (1)
  0x001a0000 ENV- Variablen (2)
  0x001c0000 ENV- Variablen (reserved for Bad Block)
  0x001e0000 ENV- Variablen (reserved for Bad Block)
  0x00200000 UBI-Device

  UBI Volumes:
  „default“:  contain environment-default values
  „rootfs1“:  UBIFS root-fs (1); contain linux kernel image
  „rootfs2“:  UBIFS root-fs (2); contain linux kernel image
  „data-ro“:  UBIFS data (read only)
  „data-rw“:  UBIFS data (read/write)

- new environment variables:
  - app_reset
    (this is only passed per cmdline to linux)
  - dvn_app_vers
    string from ramdisk description contained in the
    FIT image
  - dvn_boot_vers
    string from ubootimage description contained in the
    FIT image
  - saveparms, restoreparms, restoretmpparms, savetmpparms
    helper for saving network parameter.
  - ubiargs
    set ubi kernel cmdlinargs for booting with a ubifs rootfs
  - ubi_ubi boot with reading kernel image from ubifs, and
    use a ubifs as rootfs
