refactor(hal/usb_dwc): Add DWC OTG configuration values

Browse Source 
This commit adds a subset of the DWC OTG configuration values to the
'usb_dwc_ll.h' file. Only relevant configuration values have been added.

Some DWC OTG releated constants have also been moved from 'usb_dwc_hal.h'
to 'usb_dwc_ll.h' and renamed.
