tune-zynq.inc: Set SOC_VARIANT for zynq devices to 7z

zynq-7000 devices are mainly shipped in 2 variants.
https://www.xilinx.com/products/silicon-devices/soc/zynq-7000.html#productTable

Available SOC_VARIANT's for zynq:
"7zs" - Zynq-7000 Single A9 Core
"7z"  - Zynq-7000 Dual A9 Core

This will extend MACHINEOVERRIDES for each device variant as:
7zs --> zynq7zs
7z  --> zynq7z

This patch sets the default value of SOC_VARIANT to 7z. This can be
overriden in machine configuration to match the intended FPGA device.
