This card is based on the tea575x receiver. Use the tea575x-tuner framework
instead of reinventing the wheel.

Fix HW seek in TEA575x to work properly:
- a delay must be present after search start and before first register read
or the seek does weird things
- when the search stops, the new frequency is not available immediately, we
must wait until it appears in the register (fortunately, we can clear the
frequency bits when starting the search as it starts at the frequency
currently set, not from the value written)
- sometimes, seek remains on the current frequency (or moves only a little),
so repeat it until it moves by at least 50 kHz

The tea575x-tuner module has been updated to use the latest V4L2 framework
functionality. This also required changes in the drivers that rely on it.
The tea575x changes are:
- The drivers must provide a v4l2_device struct to the tea module.
- The radio_nr module parameter must be part of the actual radio driver,
and not of the tea module.
- Changed the frequency range to the normal 76-108 MHz range instead of
50-150.
- Add hardware frequency seek support.
- Fix broken rxsubchans/audmode handling.
- The application can now select between stereo and mono.
- Support polling for control events.
- Add V4L2 priority handling.
And radio-sf16fmr2.c now uses the isa bus kernel framework.

When reading IF_AGC_GAIN register a wrong value for the base address
register was used (STB0899_DEMOD instead of STB0899_S2DEMOD). That
lead to a wrong signal strength value on DVB-S2 transponders.

Commit b2a29b578d9c21b2e5c88020f830d3c42115c51d sets accidentally
supported delivery systems as DVB-T/T2 whilst it should be
DVB-S/S2. Due to that frontend cannot be used at all.

The raw Sony IR decoder decodes 15bit messages slightly incorrectly.
To decode the function number, it shifts the bits right by 7 so that the
function is in bits 7:1, masks with 0xFD (0b11111101), and does an 8 bit
reverse so it ends up in bits 6:0. The mask should be 0xFE to correspond
with bits 7:1 (0b11111110).
The old mask had the effect of dropping the MSB of the function number
from bit 6, and leaving the LSB of the device number in bit 7.

Currently v4l2_ctrl_add_handler adds only the controls that are owned
by the handler. This is wrong. Instead all controls, whether owned or
not, should be added.
This is also implied by the v4l2-controls.txt documentation and it is
clearly the right thing to do. The only reason this was never noticed
before is because we never did this. Only recent changes in ivtv made
this error visible because there a third handler layer was added (handler
A inherits from handler B which inherits from C, D and E). Without this
change handler A only sees the controls owned by handler B and the controls
from C, D and E are missing.

Raw IR events are passed to the raw event thread through a kfifo. The
size of the event struct is 12 bytes, and space for 512 events is
reserved in the kfifo (6144 bytes), however this is rounded down to 4096
bytes (the next power of 2) by __kfifo_alloc().
4096 bytes is not divisible by 12 therefore if the fifo fills up a third
of a record will be written in the end of the kfifo by
ir_raw_event_store() because the recsize of the fifo is 0 (it doesn't
have records). When this is read by ir_raw_event_thread() a corrupted or
partial record will be read, and in the case of a partial record the
BUG_ON(retval != sizeof(ev)) gets hit too.
According to samples/kfifo/record-example.c struct kfifo_rec_ptr_1 can
handle records of a length between 0 and 255 bytes, so change struct
ir_raw_event_ctrl to use that instead of struct kfifo.

The way discard buffer was previously handled lead
to possible races that made a buffer that was not
yet ready to be overwritten by new video data. This
is easily detected at 25fps just adding "#define DEBUG"
to enable the "memset" check and seeing how the image
is corrupted.
A new "discard" queue and two discard buffers have
been added to make them flow trough the pipeline
of queues and thus provide suitable event ordering.

The i.MX27 DMA support was introduced with the initial commit of this
driver and originally created by me. However, I never got this stable
due to the racy DMA engine and used the EMMA engine instead. As the DMA
support is most probably unused and broken in its current state, remove
it. EMMA becomes the only supported mode on i.MX27.
This also helps us get rid of another user of the legacy i.MX DMA
support and remove the dependency on ARCH_MX* macros as these are
scheduled for removal.
