* Shuffled the location of the TAMP_FWU_* macros as suggested by
Patrick

Add helper functions needed for accessing the FWU metadata which
contains information on the updatable images. These functions have
been added for the STM32MP157C-DK2 board which has the updatable
images on the uSD card, formatted as GPT partitions.

Changes since
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.

The FWU metadata structure is accessed through the driver model
interface. On the stm32mp157c-dk2 board, the FWU metadata is stored on
the uSD card. Add the fwu-mdata node on the u-boot specifc dtsi file
for accessing the metadata structure.

Changes since V5:
* Changed the logic to store the GPT partitioned block device through
a priv structure as suggested by Patrick
* Used dev_read_prop() to get the phandle_p instead of
ofnode_get_property() used earlier as suggested
, and implementations can be added based on parameters
like how the metadata partition is accessed and what type of storage
device houses the metadata.
