[v2] Makefile: socfpga: Add target to generate hex output for combined spl and dtb

[Siew Chin Lim]

From: Dalon Westergreen <dalon.westergreen at intel.com>

Add target to Makefile to generate "u-boot-spl-dtb.hex" for Intel SOCFPGA
SOC64 devices (Stratix 10 and Agilex). "u-boot-spl-dtb.hex" is hex formatted
spl with and offset of CONFIG_SPL_TEXT_BASE. It combines the spl image and dtb.
"u-boot-spl-dtb.hex" is needed to generate the final configuration bitstream
for Intel SOCFPGA SOC64 devices.
