PCIE_DW_AMD currently only targets ARCH_VERSAL2. Versal Premium Gen 2's PCIe root complex is built around the same DesignWare/MDB core, so extend the Kconfig dependency to ARCH_VERSAL and update the help text to reflect that.
Add "amd,versal2-cpm6-host" to pcie_dw_amd.c's compatible list alongside "amd,versal2-mdb-host" so the driver binds to Versal Premium Gen 2's PCIe devicetree node. versal_mem_map[] in arch/arm/mach-versal/cpu.c already maps the 0x600000000 region unconditionally as normal memory, covering the controller's DBI/ECAM window, so no mem-map changes are needed here.
