[hverkuil: drop the obsolete dvb-usb/az6027.c and dvb-usb/pctv452e.c changes]
Commit dfb9f94e8e ("[media] stk1160: Build as a module if SND is m and
audio support is selected") had to introduce some complex config dependency
handling to compile for all combinations of configs VIDEO_STK1160 and
VIDEO_STK1160_AC97.
Later, commit e36e6b5f26 ("[media] stk1160: Remove stk1160-mixer and
setup internal AC97 codec automatically") removes the config
VIDEO_STK1160_AC97, which renders the previous dependency handling
unnecessary. The commit already simplified the dependency of the remaining
config VIDEO_STK1160, but it misses the opportunity to merge VIDEO_STK1160
and VIDEO_STK1160_COMMON.
So, do that now and simplify the build config definition of the STK1160 USB
video capture support.

This reverts commit cd61f3c679. That
commit's purpose was to prevent the padding from being decoded when
userspace didn't set a selection, relying on the default one.
However, as described in the Step 6 of the Initialization procedure for
the Memory-to-Memory Stateful Video Encoder Interface [1]:
"Set the visible resolution for the stream metadata via
VIDIOC_S_SELECTION() on the OUTPUT queue if it is desired to be
different than the full OUTPUT resolution."
And from the Note:
"To avoid encoding the padding, the client needs to explicitly configure
this selection target"
Hence the behavior in the original commit doesn't follow the interface
and needs to be reverted.
This fixes the following v4l2-compliance failure observed on
mt8192-asurada-spherion:

The VI peripheral of Tegra supports capturing from MIPI CSI-2 or parallel
video (called VIP in the docs).
The staging tegra-video driver currently implements MIPI CSI-2 video
capture for Tegra210. Add support for parallel video capture (VIP) on
Tegra20. With the generalizations added to the VI driver in previous
commits, this is only a matter of adding the vip.c and tegra20.c
implementations and registering them.
Unfortunately there was no documentation available for the VI or VIP
peripherals of Tegra20 (or any other Tegra chips). This implementation has
been based entirely on the code from a vendor kernel based on Linux 3.1 and
massively adapted to fit into the tegra-video driver. Parts of this code is
definitely non-optimal to say the least (especially tegra20_vi_enable() and
the single-frame capture logic), but it was impossible to improve it.

Tegra20 supports planar YUV422 capture, which can be implemented by writing
U and V base address registers in addition to the "main" base buffer
address register.
It also supports H and V flip, which among others requires to write the
start address (i.e. the 1st offset to write, at the end of the buffer or
line) in more registers for Y and, for planar formats, U and V.
Add minimal hooks in VI to allow per-SoC optional support to those
features:
- variables in struct tegra_vi for the U and V buffer base offsets
- variables in struct tegra_vi for the Y, U and V buffer start offsets
- an optional per-soc VI operation to compute those values on queue setup

The CSI module does not handle all the MIPI lane calibration procedure,
leaving a small part of it to the VI module. In doing this,
tegra_channel_enable_stream() (vi.c) manipulates the private data of the
upstream subdev casting it to struct 'tegra_csi_channel', which will be
wrong after introducing a VIP (parallel video input) channel.
This prevents adding support for the VIP module. It also breaks the
logical isolation between modules.
Since the lane calibration requirement does not exist in the parallel input
module, moving the calibration function to a per-module op is not
optimal. Instead move the calibration procedure in the CSI module, together
with the rest of the calibration procedures. After this change,
tegra_channel_enable_stream() just calls v4l2_subdev_call() to ask for a
stream start/stop to the CSI module, which in turn knows all the
CSI-specific details to implement it.

The dvb-usb core function only checks if the returned value is
zero, so it doesn't actually matter the error code. Still, returning
-1 as an error condition is something that we don't do upstream. So,
change the logic to return -EIO in case of I2C transfer failures.
