Our platforms have 3 xhci controllers which map to 3 different phy ports.
And the three phy ports use the same driver, but the parameters are different.
So I put the parameter settings in DTS, we have 3 usb-phy nodes representing 3 phy ports.
Also, some parameters have to be adjusted for different boards.
Therefore, it is more applicable in DTS than in driver.

OK I know it doesn't make sense.
We want to disable phy suspend from mac layer.
I will try other method.

OK. I know it doesn't make sense.
