[U-Boot] [PATCH 1/2] Makefile: Add target to generate hex output for combined spl and dtb

[Dalon Westergreen]

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

Some architectures, Stratix10, require a hex formatted spl that combines
the spl image and dtb.  This adds a target to create said hex file with
and offset of SPL_TEXT_BASE.
