[meta-xilinx] [PATCH v2 4/7] u-boot-spl-zynq-init.inc: Add ZynqMP PMU binary input support

[Nathan Rossi]

Add support to provide the path of the PMU firmware to the U-Boot build
via the CONFIG_PMUFW_INIT_FILE config so that the binary can be embedded
into the boot.bin output where support is available (e.g. u-boot-xlnx).
