is_private was set right after creating each control, but the control pointer
might be NULL in case of an error. Set it after all controls were successfully
created, since that guarantees that all control pointers are non-NULL.

This patch fixes two errors that caused incorrect format detections:
The first bug is in the calculation of the vertical backporch: the combined
period of vsync and backporch must *exceed* a certain minimum value, and not
be equal to it.
The second bug is a rounding error in the reduced blanking calculation:
expand the ideal_duty_cylce to be in parts per ten thousand to avoid
rounding errors.

When streamoff is called on the context and the context
is added to the job_queue,
1] sometimes device_run receives the empty vb2 buffers (as
   v4l2_m2m_streamoff is dropping the ready queue).
2] sometimes v4l2_m2m_job_finish may not succeed as the m2m_dev->curr_ctx
   is made NULL in the v4l2_m2m_streamoff()
The above points may stop the execution of the other queued contexts.
This patch makes sure that before streamoff is executed on any context,
that context should "not be running" or "not queued" in the job_queue.
1] If the current context is running, then abort job will be called.
2] If the current context is queued, then the context will be removed from
   the job_queue.

Those boards were missing the ISDB-T support.
Most of the work on this patch were done by Alfredo.
My work here were to port this patch from Kernel 3.2 to upstream,
fix the issue caused by the set_frontend bad hook, and add the
Kconfig bits.
Tested on a X8502 board rebranded as:
"Leadership - Placa PCI-e de Captura de Vídeo Híbrida" - product code 3800.

changeset 768e6dad caused a regression on using mb86a20s
in parallel mode, as the parallel mode selection got
overriden by mb86a20s_init2.

When the frontend drivers got converted to DVBv5 API, the original
hook that tracked when a frontend is set got removed, being replaced
by an approach that would use the gate control. That doesn't work
fine with some boards. Also, the code were called more times than
desired.
Replace it by a logic that will hook the dvb set_frontend ops,
with works with both DVBv3 and DVBv5 calls.
Tested on a Mygica X8502 OEM board.

The two operations are very similar, refactor most of the code in a
helper function.

Commit b037c0fd ("media: vb2: fix
potential deadlock in mmap vs. get_userptr handling") fixes an AB-BA
deadlock related to the mmap_sem and driver locks. The same deadlock can
occur in vb2_prepare_buffer(), fix it the same way.

Note that with the rc-feedback trigger, the cir-rx trigger is now
redundant. The cir-tx trigger is not used by default; if this
functionality is desired then it should exist in rc-core, not in
a driver.
Also make sure that the led is suspended on suspend.
