acpi_pad: "processor_aggregator" name too long

cpi_device_class can only be 19 characters and a NULL terminator.

With the current name we get a buffer overflow in acpi_pad_add()
	strcpy(acpi_device_class(device), ACPI_PROCESSOR_AGGREGATOR_CLASS);

[[email protected]: call it acpi_pad, per Shaohua Li]
