usb: dwc3-of-simple: Stop using of_reset_control_array_get() directly

Use of_reset_control_array_get_optional_exclusive() instead, it is
implemented as:

  static inline struct reset_control *
  of_reset_control_array_get_optional_exclusive(struct device_node *node)
  {
          return of_reset_control_array_get(node, false, true, true);
  }

This makes the code easier to understand and removes the last remaining
direct use of of_reset_control_array_get(). No functional changes.

This change was made possible by commit f4cc91dd ("usb: dwc3:
of-simple: remove Amlogic GXL and AXG compatibles"), which made the
parameters passed to of_reset_control_array_get() constant.
