Subject: [PATCH] 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.

Fixes: f4cc91ddd856 ("usb: dwc3: of-simple: remove Amlogic GXL and AXG compatibles")
