[PULL 42/62] hw/arm/xlnx-versal-virt: rename the machine to amd-versal-virt

[Peter Maydell <peter.maydell@linaro.org>]

From: Luc Michel <luc.michel@amd.com>

To align with current branding and ensure coherency with the upcoming
versal2 machine, rename the xlnx-versal-virt machine to amd-versal-virt.
Keep an alias of the old name to the new one for command-line backward
compatibility.

-Xilinx Versal is a family of heterogeneous multi-core SoCs
+AMD Versal is a family of heterogeneous multi-core SoCs
 (System on Chip) that combine traditional hardened CPUs and I/O
 peripherals in a Processing System (PS) with runtime programmable
 FPGA logic (PL) and an Artificial Intelligence Engine (AIE).
 
+QEMU implements the Versal Series variant of Versal SoCs, with the
+``amd-versal-virt`` machine. The alias ``xlnx-versal-virt`` is kept for
+backward compatibility.

 More details here:

 The family of Versal SoCs share a single architecture but come in
 different parts with different speed grades, amounts of PL and
 other differences.
