Also, use rds_reset() now to clear data on station change since
the rds driver internal buffers are used.

* 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.
Change-Id: Idd00c94ca2fc43cf32f9223aa4530d5a02fb3454
* 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* Text is no longer updated until a complete group has been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).

There is no simple method to detect radio through the 3-wire interface, so it's
not implemented for the YH-925 for now. YH-920 always has a radio.

Actually 0x20 is the right address, the 0x22 applies to the meizu which
probably use a Chinese clone with a non-spec compliant address.

The old was doing register read/writes without calling tuner_power(), this
is broken for target with real tuner power management.

They share most of registers (except test and some extra bits), since our
driver is very basic, it is safe to relax the manufacurer & chip id check.
Change-Id: If54e8b9e0d852cd9128d5e28ff59bd2c7a55d98d
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)

This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.
