Anson Huang a048fe996b clk: imx: pllv4: add fractional-N pll support 
The pllv4 supports fractional-N function, the formula is:

PLL output freq = input * (mult + num/denom),

This patch adds fractional-N function support, including
clock round rate, calculate rate and set rate, with this
patch, the clock rate of APLL in clock tree is more accurate
than before:
