usb: dwc2: add support for APM82181 USB OTG
adds the specific compatible string for the DWC2 IP found in the APM82181 SoCs. The IP is setup correctly through the auto detection... With the exception of the AHB Burst Size. The default of GAHBCFG_HBSTLEN_INCR4 of the "snps,dwc2" can cause a system hang when the USB and SATA is used concurrently. Because the predecessor (PPC460EX (Canyonlands)) already had the same problem, this SoC can make use of the existing dwc2_set_amcc_params() function.
