Emil Lundmark 5c2f117a22 clk: imx: fix integer overflow in AV PLL round rate 
Since 'parent_rate * mfn' may overflow 32 bits, the result should be
stored using 64 bits.

The problem was discovered when trying to set the rate of the audio PLL
(pll4_post_div) on an i.MX6Q. The desired rate was 196.608 MHz, but
the actual rate returned was 192.000570 MHz. The round rate function should
have been able to return 196.608 MHz, i.e., the desired rate.

Fixes: ba7f4f557e ("clk: imx: correct AV PLL rate formula")
