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
