Some functions are powerpc specific which cause error when the
driver is used on ARM platforms.
Added micro to make them only be used on powerpc platforms.

T4240 has a errata A-008083:
Dynamic frequency switch (DFS) can hang SoC when changing
frequency of a cluster with active cores or snoop transactions.
This patch provided a workaround for this errata by putting
a cluster to PCL10 status before changing its frequency.

Freescale introduced new ARM core-based SoCs which support dynamic
frequency switch feature. DFS on new SoCs are compatible with current
PowerPC CoreNet platforms. In order to support those new platforms,
this driver needs to be slightly adjusted. The main changes include:
1. Changed the names of driver and functions in driver.
2. Added two new functions get_cpu_physical_id() and get_bus_freq().
3. Used a new way to get all the CPUs which sharing clock wire.
