different ISH client drivers to set/get private driver data.

Never directly free @dev after calling device_register(), even
if it returned an error. Always use put_device() to give up the
reference initialized.

The dev_attrs field has long been "depreciated" and is finally being
removed, so move the driver to use the "correct" dev_groups field
instead for struct bus_type.

Declare device_type structure as const as it is only stored in the
type field of a device structure. This field is of type const, so add
const to the declaration of device_type structure.

We have the %pU printf extension for doing exactly this. Saves some
.text, and is likely also a little faster.

The ISH transport layer (ishtp) is a bi-directional protocol implemented
on the top of PCI based inter processor communication layer. This layer
offers:
- Connection management
- Flow control with the firmware
- Multiple client sessions
- Client message transfer
- Client message reception
- DMA for RX and TX for fast data transfer
Refer to Documentation/hid/intel-ish-hid.txt for
overview of the functionality implemented in this layer.
