[PATCH v2 4/5] clk: lpc18xx: add NXP specific COMMON_CLK_NXP configuration symbol

[Vladimir Zapolskiy <vz@mleia.com>]

The change adds COMMON_CLK_NXP configuration symbol and enables it for
NXP LPC18XX architecture, this is needed to reuse drivers/clk/nxp
folder for NXP common clock framework drivers other than LPC18XX one.
