boot/uboot.mk: new zynqmp pmufw embeddedsw option

Browse Source 
The new BR2_TARGET_UBOOT_ZYNQMP_PMUFW_EMBEDDEDSW option will enable u-boot to
use the xilinx-embeddedsw package for building a pmufw.elf that gets included
in the generated boot.bin.

If the BR2_TARGET_UBOOT_ZYNQMP_PMUFW_EMBEDDEDSW option is enabled, then the
BR2_TARGET_UBOOT_ZYNQMP_PMUFW config for downloading a prebuilt pmufw from a
custom location will be ignored.
