Subject: [PATCH 1/2] HID: hiddev: move hiddev's minor number from struct hid_device to hiddev

We need to store the minor number each drivers. In case of hidraw, it's
minor number stores in struct hidraw. But hiddev's minor is located in
struct hid_device.

So reallocates for hiddev's minor number.
