tune-zynqmp.inc: Set default SOC_VARIANT to eg

UltraScale MPSoC is shipped in 3 device variants.
https://www.xilinx.com/products/silicon-devices/soc/zynq-ultrascale-mpsoc.html#productTable

Available SOC_VARIANT's for zynqmp:
"cg" - Zynq UltraScale+  CG Devices
"eg" - Zynq UltraScale+  EG Devices (MALI 400)
"ev" - Zynq UltraScale+  EV Devices (MALI 400 + VCU)

This will extend MACHINEOVERRIDES for each device variant as:
cg  -->  zynqmpcg
eg  -->  zynqmpeg
ev  -->  zynqmpev

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