Subject: [PATCH] ARM: 8103/1: save/restore Cortex-A9 CP15 registers on
 suspend/resume

The CP15 diagnostic register holds ARM errata bits on Cortex-A9, so it
needs to be saved/restored on suspend/resume.  Otherwise, the
effectiveness of errata workaround gets lost together with diagnostic
register bit across suspend/resume cycle.  And the CP15 power control
register of Cortex-A9 shares the same problem.

The patch adds a couple of Cortex-A9 specific suspend/resume functions
to save/restore these two Cortex-A9 CP15 registers across the
suspend/resume cycle.
