[PATCH v1 2/2] arm64: dts: xilinx: add soc-specific spi compatibles for zynqmp/versal-net

[Conor Dooley <conor@kernel.org>]

From: Conor Dooley <conor.dooley@microchip.com>

Unlike zynq, which has a specific compatible for the Cadence spi
controller, zynqmp and versal-net do not have specific compatibles.
In order to "encourage" people to use soc-specific compatibles for new
devices using this IP, add specific compatibles for these devices, with
a fallback to the existing compatible for the r1p6 version of the IP so
that there will be no functional change.
