usb: dwc2: Update bit polling functionality
Move dwc2_hsotg_wait_bit_set function to core.c so it can be used
anywhere in the code.
Added dwc2_hsotg_wait_bit_clear function in core.c.
Replace all the parts of register bit polling code with
dwc2_hsotg_wait_bit_set or dwc2_hsotg_wait_bit_clear functions
calls depends on code logic.
