machine-xilinx-overrides.inc: Provide override mechanism depending on SoC features
This patch enables to add overrides depending on the SoC capabilities.
UltraScale+ FPGA has different variants of silicon to support different
features like MALI400, VCU. Categorically there are three variants: cg
devices, eg devices(MALI 400) and ev devices (MALI 400+ VCU)
See:
https://www.xilinx.com/products/silicon-devices/soc/zynq-ultrascale-mpsoc.html#productTable
dr devices are based for UltraScale+ RFSoC
This patch allows machineoverides to be extended as zynqmp(cg|eg|ev|dr)
and mali400/vcu (based on functionality). This helps in grouping of
settings for similar SoC
This patch also adds packages to be a part of the feed based on
SOC_FAMILY and SOC_VARIANT
