[U-Boot] [PATCH] powerpc/mpc85xx: Fix the I2C bus speed error on p1022

[Yuantian.Tang at freescale.com]

From: Tang Yuantian <yuantian.tang at freescale.com>

The source clock frequency of I2C bus on p1022 is the platform(CCB)
clock, not CCB/2. The wrong source clock frequency leads to wrong
I2C bus speed setting. so, fixed it.
