based on the VID/DID values.

- 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";
};
};
