[meta-xilinx] [meta-xilinx-bsp][PATCH] machine/*.conf: Set SPL_BINARY with weak assignment ?= in machine configs

[Manjukumar Matha]

From: Jaewon Lee <jaewon.lee at xilinx.com>

Set SPL_BINARY with ?= instead of = to allow overwrite for this variable
without using forcevariable. When not using xilinx-bootbin to generate
the boot.bin, this variable should be set to '', to deploy spl boot.bin.
