Some boards like Freescale imx27-ipcam and Vista Silicon imx27_visstrim_m10 have 25MHz clocks connected to 26MHz input.

This patch allows this value to be specified from the board configuration file in the same way as it is done with 32KHz clock.

It does not break any existing board since its default value is 26MHz. Tested in imx27lite and imx27_visstrim_m10 board.
