Lookup I2C adapter using the "i2c-bus" device property on ACPI based

An example DSD describing an SFP on an ACPI based system:
Device (SFP0)
{
Name (_HID, "PRP0001")
Name (_DSD, Package ()
{
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package () {
Package () { "compatible", "sff,sfp" },
Package () { "i2c-bus", \_SB.PCI0.RP01.I2C.MUX.CH0 },Hmm, ACPI has I2cSerialBusV2() resource for this purpose. Why you are not using that?
