clk: nxp: Remove unused variable 

GCC warns:

> ../drivers/clk/nxp/clk-lpc18xx-cgu.c: In function ‘lpc18xx_pll1_recalc_rate’:
> ../drivers/clk/nxp/clk-lpc18xx-cgu.c:460:13: warning: variable ‘stat’ set but not used [-Wunused-but-set-variable]
>   460 |         u32 stat, ctrl;
>       |             ^~~~

Get rid of the (apparently) useless read from the PLL1_STAT register and
the declaration of stat.
