usb: mtu3: constify struct debugfs_reg32
mtu3_prb_regs is never changed and can therefore be made const.
This allows the compiler to put it in the text section instead of the
data section.
Before:
text data bss dec hex filename
19966 7120 0 27086 69ce drivers/usb/mtu3/mtu3_debugfs.o
After:
text data bss dec hex filename
20142 6992 0 27134 69fe drivers/usb/mtu3/mtu3_debugfs.o
