This kind of reverts 7b596416bf ("Gigabeat S: Update RDS processing to
use asynchronous I2C rather than thread."). However, requiring RDS to
run in thread context will a) allow more upcoming features and b) remove
quite some complexity from the codebase (see the diffstat here) because
Gigabeat is the only user. iMX31 should be able to handle one more
thread, as it can even run Linux.

use si4700_read() instead of si4700_read_reg() to make it clear we are
not interested in the register itself but in the cache update. Also, a
tiny bit more efficient as we save a function call and don't request a
return value we don't use anyhow.

Based on a patch by Amaury Pouly which was based on a patch from Ryan
Hitchman.
I mainly moved the code for polling into the tuner driver so it can be
reused by other targets. I added the CONFIG parameter for the polling
frequency (in ticks) to save energy. Also, I did some minor cleanups.

Patch taken from Igor Poretsky's tree.
Original clip-radio-tick.patch modified to acts only when screen is
deemed, or when recording, in order to preserve indicators
functionality.

* fmradio.c needs an implementation of tuner_get_rds_info() for the
sim (kill all the sims).
* Some macro bitflags shouldn't be seen unless HAVE_RDS_CAP is
defined.

* Remove unused bits like the radio event and simplify basic
radio interface. It can be more self-contained with rds.h only
required by radio and tuner code.
* Add post-processing to text a-la Silicon Labs AN243. The chip's
error correction can only do so much; additional checks are highly
recommended. Simply testing for two identical messages in a row
is extremely effective and I've never seen corrupted text since
doing that, even with mediocre reception.
Groups segments must arrive in order, not randomly; logic change
only accepts them in order, starting at 0.
Time readout was made a bit better but really we'd need to use
verbose mode and ensure that no errors were seen during receiving
of time and more checks would be need to have a stable PI. The
text is the important bit anyway.
* Time out of stale text.
* Text is no longer updated until a complete group has been
received, as is specified in the standard. Perhaps go back to
scrolling text lines in the radio screen?
* Add proper character conversion to UTF-8. Only the default G0
table for the moment. The other two could be added in.
* Add variants "RDS_CFG_PROCESS" and "RDS_CFG_PUSH" to allow
the option for processed RDS data to be pushed to the driver and
still do proper post-processing (only text conversion for now for
the latter).

Remove direct calls to tuner_power(...) in apps/ and let
the driver manage tuner power with the RADIO_SLEEP setting.

Theoretically, anything with the capability could implement the decoding
action in an ISR on any radio chip supporting RDS.

This removes the tuner-specific region structs and makes each driver use the common one (which is now extended with a deemphasis field)
