Resets the entire platform.
@param[in] ResetType The type of reset to perform.
@param[in] ResetStatus The status code for the reset.
@param[in] DataSize The size, in bytes, of WatchdogData.
@param[in] ResetData For a ResetType of EfiResetCold, EfiResetWarm, or EfiResetShutdown
the data buffer starts with a Null-terminated string, optionally
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 is only valid if ResetStatus is something
other than EFI_SUCCESS unless the ResetType is EfiResetPlatformSpecific
where a minimum amount of ResetData is always required.
