usb: gadget: udc: renesas_usb3: make const array max_packet_array static
Don't populate the const array max_packet_array on the stack, instead make
it static. Makes the object code smaller by over 90 bytes:
Before:
text data bss dec hex filename
34337 5612 128 40077 9c8d renesas_usb3.o
After:
text data bss dec hex filename
34149 5708 128 39985 9c31 renesas_usb3.o
(gcc version 7.2.0 x86_64)
