The g_reg and s_reg calls worked properly if acting on subdev registers (such
as the au8522), but didn't work against the au0828 itself. Copy the logic
over from em28xx.

The quality register only has relevant data in bits 2-0, so discard the
other bits (which results in a value being printed that is consistent with
the expected 0-7 range).

The logic as written would *never* actually return an error condition, since
the loop would run until the counter hit zero but the check was for a value
less than zero.

added analog support). Reproduce Mauro's fix from the em28xx driver in
au0828.

The au8522 driver was broken into three modules (dig, decoder, common), and
as a result the debug modprobe option doesn't work for any of the common
functions.
Copy the module macros over to the common module so that the debug option
works again.

calibration if reset and firmware load was
performed. Also because the called function is now a no-op if the firmware
is already loaded, the caller no longer needs to invoke is_firmware_loaded().

for a board that has the au0828/au8522 but doesn't have digital
support implemented (because the i2c_gate_ctrl callback is being set in
the DVB attach). However given how few different models are in circulation,
this can be deferred until such a situation arises (if ever).

This patch addresses a couple of cases where I forgot to pop open the gate
when in analog mode (a correlary to fix the change made in patch
1c58d5b4a5fca42dce5428bd79b9405878017735).

There are no cases where a control message is ever sent to the au0828 with
an actual buffer defined. Remove the reference to dev-ctrlmsg, which
currently requires us to hold a mutex since it is shared with the read
function.

Make the firmware speedup work for the 5000c as well as the original
xc5000. This cuts firmware load time in half.

Put a hack in place to speed up the firmware load in the case that the
xc5000 has just been reset. The chip can safely do 400 KHz in this mode,
while in normal operation it can only do 100 KHz.
This reduces the firmware load time from 6.9 seconds to 4.2.
