[PATCH v2] i2c-imx: Add missing preporcessor directives

[Andrey Smirnov]

On non-PowerPC platforms call to i2c_fsl_set_clk() will try to obtain
I2C clock freqency from i2c_fsl->clk, however that field would not be
initialized if CONFIG_COMMON_CLK is not set. This patch makes sure
that i2c_fls_set_clk() is a no-op on non-PPC targets when
CONFIG_COMMON_CLK is not set
