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.
