powerpc/powernv: Add __init attribute to eligible functions Some functions defined in 'arch/powerpc/platforms/powernv' are deserving of an `__init` macro attribute. These functions are only called by other initialization functions and therefore should inherit the attribute. Also, change function declarations in header files to include `__init`.

powerpc/powernv: Move opal_power_control_init() call in opal_init(). opal_power_control_init() depends on opal message notifier to be initialized, which is done in opal_init()->opal_message_init(). But both these initialization are called through machine initcalls and it all depends on in which order they being called. So far these are called in correct order (may be we got lucky) and never saw any issue. But it is clearer to control initialization order explicitly by moving opal_power_control_init() into opal_init().

powerpc/powernv: Add poweroff (EPOW, DPO) events support for PowerNV platform This patch adds support for OPAL EPOW (Environmental and Power Warnings) and DPO (Delayed Power Off) events for the PowerNV platform. These events are generated on FSP (Flexible Service Processor) based systems. EPOW events are generated due to various critical system conditions that require system shutdown. A few examples of these conditions are high ambient temperature or system running on UPS power with low UPS battery. DPO event is generated in response to admin initiated system shutdown request. Upon receipt of EPOW and DPO events the host kernel invokes orderly_poweroff() for performing graceful system shutdown.

powerpc/powernv: reboot when requested by firmware Use orderly_reboot so userspace will to shut itself down via the reboot path. This is required for graceful reboot initiated by the BMC, such as when a user uses ipmitool to issue a 'chassis power cycle' command.

powerpc/powernv: Add OPAL soft-poweroff routine Register a notifier for a OPAL message indicating that the machine should prepare itself for a graceful power off. OPAL will tell us if the power off is a reboot or shutdown, but for now we perform the same orderly_poweroff action.
