[media] dib0700: NEC scancode cleanup

the RC RX packet is defined as:

        struct dib0700_rc_response {
		...
                                u8 not_system;
                                u8 system;
		...
                u8 data;
                u8 not_data;

The NEC protocol transmits in the order:
        system
        not_system
        data
        not_data

Note that the code defines the NEC extended scancode as:

        scancode = be16_to_cpu(poll_reply->system16) << 8 | poll_reply->data;

i.e.

        scancode = poll_reply->not_system << 16 |
                   poll_reply->system     << 8  |
                   poll_reply->data;

Which, if the order *is* reversed, would mean that the scancode that
gets defined is in reality:

        scancode = poll_reply->system     << 16 |
                   poll_reply->not_system << 8  |
                   poll_reply->data;

Which is the same as the order used in drivers/media/rc/ir-nec-decoder.c.

This patch changes the code to match my assumption (the generated scancode
should, however, not change).
