Resets the entire platform.
This service is a wrapper for the UEFI Runtime Service ResetSystem().
The ResetSystem()function resets the entire platform, including all processors and devices,and reboots the system.
Calling this interface with ResetType of EfiResetCold causes a system-wide reset. This sets all circuitry within
the system to its initial state. This type of reset is asynchronous to system operation and operates without regard
to cycle boundaries. EfiResetCold is tantamount to a system power cycle.
Calling this interface with ResetType of EfiResetWarm causes a system-wide initialization. The processors are set to
their initial state, and pending cycles are not corrupted. If the system does not support this reset type, then an
EfiResetCold must be performed.
Calling this interface with ResetType of EfiResetShutdown causes the system to enter a power state equivalent to the
ACPI G2/S5 or G3 states. If the system does not support this reset type, then when the system is rebooted, it should
exhibit the EfiResetCold attributes.
The platform may optionally log the parmeters from any non-normal reset that occurs.

followed by additional binary data. The string is a description that the
caller may use to further indicate the reason for the system reset. ResetData
