[U-Boot] [PATCH 4/6] Makefile:Add u-boot-with-spl-pbl.bin target for SPL

[Prabhakar Kushwaha]

This image combines the pbl format of SPL with and U-Boot. This is a
convenient way of having a single image to program on indirect boot source.

Corenet platforms like T4240, P4080 etc have PBL hardware which read data
in PBL format and copy to internal SRAM for further execution.
This image configures DDR, copy u-boot to DDR and transfer the control.
