[PATCH] clk: imx: pll14xx: fix recalc_rate for negative kdiv

> kdiv is a signed 16 bit value in the DEV_CTL1 register. Commit
> 53990cf9d5b4 ("clk: imx: pll14xx: consolidate rate calculation") changed
> the kdiv variable from a short int to just int. When the value read from
> the DIV_CTL1 register is assigned directly to an int the sign of the value
> is lost resulting in incorrect results when the value is negative. Adding
> a s16 cast to the register value fixes the issue.
