[U-Boot] [PATCH v2] board/fsl/lx2160a: Fix MC firmware loading during SD boot

[Pankaj Bansal]

Issue: 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

Cause: mc 10.14.3 file size is 1064880, the value is 0x820 blocks which
is more than 0x800. The default DPC loading address 0x80100000 has overlap
with MC loading address 0x80000000, since the size of MC is over 1MB.

Fix: update the MC and dpc address as per their addresses in XSPI flash.
i.e. in xspi flash MC address is 0x20a00000 so corresponding address in
dram when loading MC firmware from mmc is 0x80a00000. similarly dpc is @
0x20e00000 in xspi flash and 0x80e00000 in dram when loaded from mmc.

This same approach is being followed in other cases also in same file,
e.g. esbc_validate 0x80740000 <=> esbc_validate 0x20740000

On same lines modify the address of dpl to 0x80d00000

Notes:
    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
