drivers: virt_ivshmem: Allow multiple instances of ivShMem devices. - Supporting multiple instances of ivShMem virtual devices. - Introduces DT based configuration for ivShMem devices. - Add DTS overlay file to test new multiple ivshmem instance capability. - Enable BDF unspecified device initialization. (limited to one instance. An improved version of pcie_bdf_lookup() will come soon that fixes this limitation) - Make PCIE DTS file macros available for a proper ivshmem device properties parsing. Sample for dts file: pcie0 { label = "PCIE_0"; #address-cells = <1>; #size-cells = <1>; compatible = "intel,pcie"; ranges; ivshmem0: ivshmem@800 { compatible = "qemu,ivshmem"; reg = <PCIE_BDF_NONE PCIE_ID(0x1af4,0x1110)>; label = "IVSHMEM"; status = "okay"; }; }; Signed-off-by: Michael Schmidt <michael1.schmidt@intel.com>
