uboot: zynqmp: generate SPL image with PMUFW binary
In order to boot on the Xilinx ZynqMP SoCs, U-Boot SPL requires a recent PMU firmware loaded. Instruct U-Boot to add pmufw.bin to the boot.bin file together with U-Boot SPL, and the boot ROM will load both. For this to work properly, a patch to U-Boot is needed. However this patch must be applied by each defconfig that wishes to use BR2_TARGET_UBOOT_ZYNQMP_PMUFW. If it were in boot/uboot/ to be applied unconditionally, it would break the build for configs using a U-Boot version higher than 2018.7-rc1 where the patch is already applied.
