[U-Boot] [PATCH 24/31] powerpc/mpc85xx: add setting of clock-frequency for mpic node

[York Sun]

From: Wang Dongsheng <dongsheng.wang at freescale.com>

Set the device tree property associated with the mpic source
frequency. The frequency is used for mpic timer.
the mpic timer use CCB/2 frequency on freescale corenet platform,
other freescale platform use CCB frequency.
