[U-Boot] [PATCH v5] board/fsl/lx2160a: Fix MC firmware loading during SD boot

[Pankaj Bansal]

during SD boot, following error comes:
  MMC read: dev # 0, block # 20480, count 2048 ... 2048 blocks read: OK

  MMC read: dev # 0, block # 28672, count 2048 ... 2048 blocks read: OK
  fsl-mc: ERR: Bad firmware image (bad FIT header)
  Hit any key to stop autoboot:  0

it's occurring because mc 10.14.3 file size is 1064880, which means 0x820
SD blocks which is more than 0x800 blocks (1MB). This results in DPC
loading address 0x80100000 overlapping with MC loading address 0x80000000.

so, update the MC/dpl/dpc addresses as per their addresses in SD card.
Assuming that SD card block size is 512 bytes and 0x0 block in SD card
would get loaded at 0x80000000 (DDR base address), this gives following
addresses for various binaries:

Binary | SD block | DDR offset
------------------------------
MC     | 0x5000   | 0x80a00000
DPL    | 0x6800   | 0x80d00000
DPC    | 0x7000   | 0x80e00000

Notes:
    V5:
    - Add 2019 in Copyright year
    V4:
    - Modify the commit message to remove any reference to Flexspi flash
    V3:
    - modify the commit message.
    - remove issue/cause/fix from message.
    V2:
    - reduce the mc firmware size blocks from 0x1800 to 0x1200, to save on
      boot time
    - Fix the commit message to indicate that the patch is for LX2160A boards
      only and for SD boot only
