usb: gadget: udc: renesas_usb3: lock for PN_ registers access
commit 940f538a100c84c6e72813e4ac88bd1753a86945 upstream.
This controller disallows to change the PIPE until reading/writing
a packet finishes. However. the previous code is not enough to hold
the lock in some functions. So, this patch fixes it.
