    Freescale Android BSP doesn't support TVin chips, this patch enabled the adv7180 chip for Android.

    The followed functions are supported:

    1) Android camera application can preview the tvin.
    2) De-interlace was supported in Android overlay.
    3) VDI split mode was support to preview TVin on high resolution display.
    4) Support auto-detect PAL and NTSC mode.


Some limitation for the patch:

-- The android camera applition doesn't support PAL/NTSC switch on the fly.
   (After switched the input signal, stop camera application and re-start it; unit test
    application "mxc_v4l2_tvin" supports the on the fly switch.)

-- For VDI split mode, only high motion was supported. When output preview
   Resolution is high than 968*1024, only high motion (-m 2) can be used.

-- Android camera applition video recording was not supported.
