feat(stm32mp1): add GUID values for updatable images

With the FWU multi bank feature enabled, the identification of
firmware image type is done using the image type GUID instead of
binary_type field.

Add GUID values for the FIP image which can be updated through
the FWU firmware update feature. The GUID values are used in
identifying the firmware images.
