usb: dwc3: Support quirk for writing high-low order
There's the limitation of Synopsys dwc3 controller with ERST programming in supporting separate ERSTBA_HI and ERSTBA_LO programming. It's supported when the ERSTBA is programmed ERSTBA_HI before ERSTBA_LO. But, writing operations in xHCI is done low-high order following xHCI spec. xHCI specification 5.1 "Register Conventions" states that 64 bit registers should be written in low-high order. Synopsys dwc3 needs workaround for high-low order. That's why adding new quirk is needed to support this.
