clk: lpc32xx: fix compilation warning
Remove the following false positives compilation warning:
- drivers/clk/nxp/clk-lpc32xx.c: In function 'lpc32xx_clk_register':
warning: 'hw' may be used uninitialized in this function [-Wmaybe-uninitialized]
- drivers/clk/nxp/clk-lpc32xx.c: In function 'clk_hclk_pll_round_rate':
warning: 'p' may be used uninitialized in this function [-Wmaybe-uninitialized]
warning: 'n' may be used uninitialized in this function [-Wmaybe-uninitialized]
warning: 'm' may be used uninitialized in this function [-Wmaybe-uninitialized]
Tested using gcc version 4.7.3.
