[PATCH v9 05/15] stm32mp1: dk2: Add image information for capsule updates

[Sughosh Ganu]

Enabling capsule update functionality on the platform requires
populating information on the images that are to be updated using the
functionality. Do so for the DK2 board.

Changes since V8:
* Use STM32MP_FIP_IMAGE_GUID for the FIP GUID value as suggested by
  Yann
