media: coda: implement ENUM_FRAMEINTERVALS
v4l2-compliance complains about S_PARM being supported, but not
ENUM_FRAMEINTERVALS.
Report a continuous frame interval even though the hardware only
supports 16-bit numerator and denominator, with min/max values
that can be programmed into the mailbox registers.
