USB: add runtime frame_no quirk for big-endian OHCI
Add OHCI big endian frame_no quirk. The frame_no value stored in the
HCCA is a 16 bit field at a specific offset, but since not all CPUs can
do 16-bit memory accesses it's used as a 32 bit field. And that's why
big-endian OHCI must shift 16 bits ... unless the spec is not followed.
Currently there's one MPC52xx platform that doesn't need the shift. This
patch adds a new "big endian frame_no" quirk to control that at runtime.
