dwc3: add more quirks and checks

Rather than just printing the Global SNPS ID Register store it as well
so we can do a version check later.
In addition, for debugging purposes, read the Global Hardware Parameters
Registers and print them.

Based on the snpsid disable an XHCI feature using a quirk prepared
in 447c418da03454a2a00bc115a69c62055a6d5272.
Add the "snps,dis_u3_susphy_quirk" quirk and handle Suspend USB3.0 SS PHY
after power-on-reset/during core initialization (suggested to be cleared)
based on the DWC3_GHWPARAMS0 register.
