usb: dwc3: qcom: Refactor IRQ handling in glue driver

Browse source

On multiport supported controllers, each port has its own DP/DM and
SuperSpeed (if super speed capable) interrupts. As per the bindings,
their interrupt names differ from single-port ones by having a "_x"
added as suffix (x being the port number). Identify from the interrupt
names whether the controller is a multiport controller or not.
Refactor dwc3_qcom_setup_irq() call to parse multiportinterrupts along
with non-multiport ones accordingly.
