Currently, V4L uses a scancode table whose index is the scancode and
the value is the keycode. While this works, it has some drawbacks:

1) It requires that the scancode to be at the range 00-7f;

2) keycodes should be masked on 7 bits in order for it to work;

3) due to the 7 bits approach, sometimes it is not possible to replace
the default keyboard to another one with a different encoding rule;

4) it is different than what is done with dvb-usb approach;

5) it requires a typedef for it to work. This is not a recommended
Linux CodingStyle.

This patch is part of a larger series of IR changes. It basically
replaces the IR_KEYTAB_TYPE tables by a structured table:
struct ir_scancode {
       u16     scancode;
       u32     keycode;
};

This is very close to what dvb does. So, a further integration with DVB
code will be easy.

While we've changed the tables, for now, the IR keycode handling is still
based on the old approach.

The only notable effect is the redution of about 35% of the ir-common
module size:

   text    data     bss     dec     hex filename
   6721   29208       4   35933    8c5d old/ir-common.ko
   5756   18040       4   23800    5cf8 new/ir-common.ko

In thesis, we could be using above u8 for scancode, reducing even more the size
of the module, but defining it as u16 is more convenient, since, on dvb, each
scancode has up to 16 bits, and we currently have a few troubles with rc5, as their
scancodes are defined with more than 8 bits.

This patch itself shouldn't be doing any functional changes.

I don't have enough time. This work could be a starting point, but it can be

 - SAA7134 for TV mode uses DemDec mode (32kHz)
 - Radio works in 32kHz only
 - When recording 48kHz from Line1/Line2, switching of capture source to TV

Since i2c autoprobing is no longer supported by v4l2 we need to make sure
that the i2c modules are linked before the v4l2 modules. The v4l2 modules
now rely on the presence of the i2c modules, so these must have initialized
themselves before the v4l2 modules.

The exception is the ir-kbd-i2c module, which is the only one still using
autoprobing. This one should be loaded at the end of the v4l2 module. Loading
it earlier actually causes problems with tveeprom. Once ir-kbd-i2c is no
longer autoprobing, then it has to move up as well.

This is only an issue when everything is compiled into the kernel.

The i2c quirk in the saa7134_i2c_xfer function does a bogus write
to i2c address 0xfd, to work around a bug in the silicon that
affects read transactions.

Unfortunately, this hack is not working properly, since the bogus
write is to 0xfd, an invalid i2c address.  Fix this quirk by using
an actual valid i2c address, 0xfe, which is still unlikely to be
used as an i2c address for any actual i2c client.

This is required in order to properly communicate with a TDA10048
DVB-T demod located at i2c address 0x10 on the primary i2c bus.

Let card drivers probe for IR receiver devices and instantiate them if
found. Ultimately it would be better if we could stop probing
completely, but I suspect this won't be possible for all card types.

There's certainly room for cleanups. For example, some drivers are
sharing I2C adapter IDs, so they also had to share the list of I2C
addresses being probed for an IR receiver. Now that each driver
explicitly says which addresses should be probed, maybe some addresses
can be dropped from some drivers.

Also, the special cases in saa7134-i2c should probably be handled on a
per-board basis. This would be more efficient and less risky than always
probing extra addresses on all boards. I'll give it a try later.
