This patch changes the manager ops callbacks from accepting the subdrv
device pointer to taking a pointer to the manager. This will allow us
to move closer to decoupling manager/display from subdrv, and subsequently
decoupling the crtc/plane from the encoder.
Signed-off-by: Sean Paul <seanpaul at chromium.org>

Changes in v2:
- Instead of passing context, pass manager
- Properly assign ctx->dev in fimd driver
Changes in v3:
- Added vidi implementation
