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.
