conf: machine: Apply U-boot fragment configs for AM62P Display Cluster Image

Browse Source 
- For AM62P tisdk-display-cluster image[1], Splash Screen is handled by SBL[2].
Hence, disable the A53 based U-boot Splash Screen using the am62px_evm_prune_splashscreen.config
fragment present in ti-u-boot tree.

- Apply a check on DISPLAY_CLUSTER_ENABLE variable[3] to ensure we apply am62px_evm_prune_splashscreen.config
only incase of tisdk-display-cluster image as tisdk-default-image will still have the A53 based U-boot Splash Screen.
