HID: hiddev: reallocate hiddev's minor number
We need to store the minor number each drivers. In case of hidraw, the minor number is stored stores in struct hidraw. But hiddev's minor is located in struct hid_device. The hid-core driver announces a kernel message which driver is loaded when HID device connected, but hiddev's minor number is always zero. To proper display hiddev's minor number, we need to store the minor number asked from usb core and do some refactoring work (move from hiddev.c to hiddev.h) to access hiddev in hid-core.
