[PATCH v4] Add make feature support for SoCFPGA Handoff

[PATCH v4] Add make feature support for SoCFPGA Handoff

[Brian Sune]

Introduce socfpga_gen5_handoff_prepare target in U-Boot Makefile
Automatically detects Altera/Intel SoCFPGA boards from .config
Checks for presence of hps_isw_handoff folder and .hiof files
Runs BSP generator script tools/cv_bsp_generator/cv_bsp_generator.py 
if files exist
Non-blocking: prepare continues even if handoff folder or files are missing
HANDOFF_PATH user define: override the auto detection in board folder
