[PATCH] media: bcm2835-unicam: Fix querycap multiple caps

[Eugen Hristev]

The unicam exposes two video nodes, one for image, another for metadata.
Querycap should return the right caps for the respective node, not both.

video0:

Capabilities     : 0xa4200001
        Video Capture
        I/O MC
        Streaming
        Extended Pix Format
        Device Capabilities
Device Caps      : 0x24200001
        Video Capture
        I/O MC
        Streaming
        Extended Pix Format

video1:

Capabilities     : 0xa4a00000
        Metadata Capture
        I/O MC
        Streaming
        Extended Pix Format
        Device Capabilities
Device Caps      : 0x24a00000
        Metadata Capture
        I/O MC
        Streaming
        Extended Pix Format
