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.
