I believe the UM says that 64 <= m <= 511.  Although the above seems
to work on 5250 and 5420, it might be better to use a table that
conforms to the constraint on m:

PLL_36XX_RATE(192000000, 64, 2, 2, 0),
PLL_36XX_RATE(180633600, 90, 3, 2, 20762),
PLL_36XX_RATE(180000000, 90, 3, 2, 0),
PLL_36XX_RATE(73728000, 98, 2, 4, 19923),
PLL_36XX_RATE(67737600, 90, 2, 4, 20762),
PLL_36XX_RATE(49152000, 98, 3, 4, 19923),
PLL_36XX_RATE(45158400, 90, 3, 4, 20762),
PLL_36XX_RATE(32768000, 131, 3, 5, 4719)

Thanks,
Andrew
