Fixed behavior for devices, that supported High-speed by correct init and configuration of HCFG and HFIR registers.

Might be tested on nRF54LM20.

Note: Control transfers only

Add initial usb host driver for Synopsys DWC2 with vendor quirks.

Add explicit init and configuration of HCFG and HFIR for Host.
When new device is connected, the PHY clock should be confgured
according to the maximum supported speed by hardware and the
port speed after reset.
