[PATCH v2] ARM: webasto-ccbv2: Add variant with 512MB RAM

[Holger Assmann <h.assmann@xxxxxxxxxxxxxx>]

Add variant for 512MB RAM board.

v1 -> v2:

 by Rouven Czerwinski <r.czerwinski@xxxxxxxxxxxxxx>:
  - just ship one single firmware version, depending on the underlying
    board variant

 by Ahmad Fatoum <a.fatoum@xxxxxxxxxxxxxx>:
  - account for the 512MB variant by hard-coding memsize == SZ_512

Signed-off-by: Holger Assmann <h.assmann@xxxxxxxxxxxxxx>
