Microchip AT91 SoC updates for v6.8

Browse Source 
It contains:
 - one patch for secure mode to set the target power management mode in
   initialization process as at91_pm_begin() is not called on suspend
   path while in secure mode; this is necessary for different drivers to
   know which suspend mode the system is going to switch to and act
   accordingly
