[PATCH] clk: imx31: fix potential stack corruption on clock initialization

[Vladimir Zapolskiy]

Function mx31_clocks_init() is called during clock intialization on
legacy boards with reference clock frequency passed as its input
argument, this can be verified by examination of the function
declaration found in arch/arm/mach-imx/common.h and actual function
users which include that header file.
