usb: renesas_usbhs: make array type_array static const 

Array type_array can be made static const rather than being
populated on the stack. Makes the object code smaller:

Before:
   text    data     bss     dec     hex filename
   8087    1496       0    9583    256f drivers/usb/renesas_usbhs/pipe.o

After:
   text    data     bss     dec     hex filename
   7883    1584       0    9467    24fb drivers/usb/renesas_usbhs/pipe.o
