[media] au0828: improve I2C speed

Commits 21dc61d3c0a4 and 7a1dd50b89d4 reduced the board I2C
speed to 20 MHz by default, due to a I2C stretch issue:
while xc5000 uses i2c stretch when a command is sent to it,
au0828 doesn't support this feature.

However, this is needed only for Xceive tuners. The other
I2C devices can work at the max speed.

So, revert the workarounds at board level, handling it at
I2C level, only when talking with xc5000.

[media] v4l2-ctrls: fix rounding calculation

Commit 958c7c7e65 ("[media] v4l2-ctrls: fix corner case in round-to-range code") broke
controls that use a negative range.

The cause was a s32/u32 mixup: ctrl->step is unsigned while all others are signed. So
the result type of the expression '(ctrl)->maximum - ((ctrl)->step / 2)' became unsigned,
making 'val >= (ctrl)->maximum - ((ctrl)->step / 2)' true, since '((u32)-128) > 128'
(if val = -128, maximum = 128 and step = 1).

So carefully cast (step / 2) to s32.

There was one cast of step to s32 where it should have been u32 because both offset and
step are unsigned, so casting to signed makes no sense there. You do need a cast to u32
there, because otherwise architectures that have no 64-bit division start complaining
(step is a u64).

[media] rc-core: document the protocol type

Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.

This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

[media] dib0700: NEC scancode cleanup

the RC RX packet is defined as:

        struct dib0700_rc_response {
...
                                u8 not_system;
                                u8 system;
...
                u8 data;
                u8 not_data;

The NEC protocol transmits in the order:
        system
        not_system
        data
        not_data

Note that the code defines the NEC extended scancode as:

        scancode = be16_to_cpu(poll_reply->system16) << 8 | poll_reply->data;

i.e.

        scancode = poll_reply->not_system << 16 |
                   poll_reply->system     << 8  |
                   poll_reply->data;

Which, if the order *is* reversed, would mean that the scancode that
gets defined is in reality:

        scancode = poll_reply->system     << 16 |
                   poll_reply->not_system << 8  |
                   poll_reply->data;

Which is the same as the order used in drivers/media/rc/ir-nec-decoder.c.

This patch changes the code to match my assumption (the generated scancode
should, however, not change).
