usb: musb: Constify struct musb_fifo_cfg
'struct musb_fifo_cfg' are not modified in these drivers.
Constifying these structures moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename

After:
=====
text data bss dec hex filename
