This patch adds the logic to pick "dss_display_share.wkup-r5f0_0.release.strip.out"
DM firmware for AM62P Display cluster usecase in meta-ti-bsp.

Until now this logic was maintained in meta-tisdk layer [0]
as binman had issues in overriding the custom DM firmware & additional
hack of passing `BINMAN_ALLOW_MISSING=1` was needed to bypass the same [1]

With [2], the DM firmware selection logic is now fixed in ti-u-boot.
Hence, the DM firmware selection logic can now be maintained in meta-ti-bsp.

The firmware selection logic is tied to DISPLAY_CLUSTER_ENABLE. Hence, it
doesn't affect any users who are using the default "ipc_echo_testb_mcu1_0_release_strip.xer5f"
firmware shipped with tisdk-default-image.

We already have references of DISPLAY_CLUSTER_ENABLE in meta-ti-bsp for AM62P [3]
& DM firmware selection logic was the only piece carried in meta-tisdk until now.
