Staging: hv: Transform PDEVICE_OBJECT and DEVICE_OBJECT typedefs into their corresponding structs

Remove typedef DEVICE_OBJECT and use a struct named hv_device instead.
Remove typedef PDEVICE_OBJECT which aliases a pointer and use
struct hv_device * instead.

Here is the semantic patch to perform this transformation:
