sbshc: acpi_device_class "smbus_host_controller" too long

From: Dan Carpenter <[email protected]>

acpi_device_class can only be 19 characters and a NULL terminator.

With the current name we get a buffer overflow in acpi_smbus_hc_add() when we do:

	strcpy(acpi_device_class(device), ACPI_SMB_HC_CLASS);
