dt-bindings: usb: mtk-xhci: add a property for Gen1 isoc-in transfer issue
For Gen1 isoc-in endpoint on controller before about SSUSB IPM v1.6.0, it
still send out unexpected ACK after receiving a short packet in burst
transfer, this will cause an exception on connected device, specially for
a 4k camera.
Add a quirk property "rx-fifo-depth" to work around this hardware issue,
prefer to use 3k bytes;
The side-effect is that it may cause performance drop about 10%, including
bulk transfer.
