This patch converts the gp8psk module to use the S2API.
It pretends to be DVB-S2 capable in order to allow the various
supported modulations (8PSK, QPSK-Turbo, etc), and keep software
compatibility with the S2API patches for Mythtv and VDR.

The init_fw option was broken for the HVR-950q because we would call the reset
callback inside of dvb_attach() and the callback had not been setup yet.
Michael Krufky (who added the init_fw feature) says it's no longer required,
so just remove the option completely.

- em28xx_init_dev() were unlocking without a previous lock;
- some read ioctls need to lock after the removal of KBL, since a write

- keep the device locked during all device initialization;

The indirect registers at 0x1c/0x1d control frame settings. If we
leave the values at 0x0a and 0x0b at their reset-time defaults, frame
data from the camera matches the UVC payload format. This lets us
better reassemble the data into frames and know when data was lost.
This also lets us relax the bulk_size requirement from 600K to 2K,
which should help systems on with limited RAM (like the PS3).

This is a port of the fixes Hans Verkuil made for ivtv/cx25840:
The service_set field was used to determine whether raw or sliced VBI was
desired. This is incorrect since it is perfectly valid to select sliced VBI
with a service_set of 0.
Instead the driver should check on VIDIOC_S_FMT whether the type
field matches the raw or sliced VBI type.
Updated the cx18 driver accordingly, including an additional check in
cx18_start_v4l2_encode_stream() that didn't exist in ivtv.

cx18: Avoid making firmware API calls with the queue lock held. The source
of MPEG strem corruption when not holding the queue lock was found to be that
the MPEG buffer could be retrieved by the user app before it was sync'ed for
the host cpu. Incoming buffers are now sync'ed before being put on q_full and
releasing the queue lock. We can thus avoid the sometimes lengthy call to
the firmware for CPU_DE_SET_MDL while holding the queue lock, so we can get
better performance.
