clk: nxp: Fix pll0 rate check condition in LPC18xx CGU driver

[ Upstream commit 1624dead9a4d288a594fdf19735ebfe4bb567cb8 ]

The conditional check for the PLL0 multiplier 'm' used a logical AND
instead of OR, making the range check ineffective. This patch replaces
&& with || to correctly reject invalid values of 'm' that are either
less than or equal to 0 or greater than LPC18XX_PLL0_MSEL_MAX.

This ensures proper bounds checking during clk rate setting and rounding.
