This patch set touches other psci drivers, such as

But the changes are quite slightly, take the psci_sun7i.S for example, changes after all patches are like this:

This patch set contains two parts: ARMv7 PSCI common framework: fix some issues and add v1.0 support NXP (was Freescale) LS102XA: codes enhancement and add v1.0 implementation
Changes since v1:
- re-organize psci_cpu_on_common, this code should be called by each platform's
psci_cpu_on, should not be a function calling each psci_cpu_on, all related functions are updated due to this change
- update some registers usage, e.g. if r10 is used without push/pop, u-boot
cannot launch rt-kernel
- update some comments to be clearer, re-organize all patches for easier review
- add patch to check already_on or on_pending for LS102XA
