cpufreq: qoriq: Make the driver usable on all QorIQ platforms
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.
