[PATCH v11 04/28] media: platform: Change the fixed device node number to unfixed value

The driver can be instantiated multiple times, e.g. for a decoder and
an encoder. Moreover, other drivers could coexist on the same system.
This makes the static video node number assignment pointless, so switch
to automatic assignment instead.
