feat(stm32mp1): add logic to pass the boot index to the Update Agent

With the FWU Multi Bank update feature, the platform can boot from one
of multiple banks(partitions). Pass the value of bank from which the
platform has booted as boot index to the Update Agent. The Update
Agent will match this boot index value against the active_index field
in the metadata, and update the metadata if there is a mismatch.

Fow now, the mechanism to pass the boot index is platform specific. On
the STM32MP1 platform, the boot index value is passed through a
memorey mapped TAMP register on the SoC.

feat(stm32mp1): add logic to select the images to be booted

With the FWU multi bank boot feature enabled, the platform can boot
from one of the multiple banks(partitions) containing the firmware
images. The bank whose firmware components are to be booted is read
from the FWU metadata structure -- the image to be booted is thus
derived by reading the metadata.

Read the metadata and set the image spec of the corresponding image
type to point to the partition from which the image is to be booted.
