Subject: [PATCH v5 0/3] Add support for runtime features

Add support for runtime feature configuration by using the IOCTL
 calls. The user can enable or disable as well as can configure the
 runtime features. The support is added for the over temperature and
 external watchdog. The user can configure the over temperature limit
 and external watchdog timer interval at runtime by using PM_IOCTL
 calls.
 
Also, added support for sysfs interface for runtime feature
configuration for the over temperature and external watchdog features.

Added zynqmp_devinfo structure to handle multiple driver instances
 when accessed by multiple devices.
