Use shiny new acpi_dev_present() and remove all the boilerplate
to search for a particular ACPI device. No functional change.

This reverts commit 7290006d8c.
Through the regression report, it was revealed that the
tpacpi_led_set() call to thinkpad_acpi helper doesn't only toggle the
mute LED but actually mutes the sound. This is contradiction to the
expectation, and rather confuses user.
According to Henrique, it's not trivial to judge which TP model
behaves "LED-only" and which model does whatever more intrusive, as
Lenovo's implementations vary model by model. So, from the safety
reason, we should revert the patch for now.

This patch adds the missing flag to enable "Mute-LED Mode" mixer enum
ctl for Thinkpads that have also the software mute-LED control.

Now some codes and functionalities of hda_codec struct are moved to
hdac_device struct. A few basic attributes like the codec address,
vendor ID number, FG numbers, etc are moved to hdac_device, and they
are accessed like codec->core.addr. The basic verb exec functions are
moved, too.

Use dev_err() and co for messages from HD-audio controller and codec
drivers. The codec drivers are mostly bound with codec objects, so
some helper macros, codec_err(), codec_info(), etc, are provided.
They merely wrap the corresponding dev_xxx().
There are a few places still calling snd_printk() and its variants
as they are called without the codec or device context.

The current code for controlling mic mute LED in patch_sigmatel.c
blindly assumes that there is a single capture switch. But, there can
be multiple multiple ones, and each of them flips the state, ended up
in an inconsistent state.
For fixing this problem, this patch adds kcontrol to be passed to the
hook function so that the callee can check which switch is being
accessed. In stac_capture_led_hook(), the state is checked as a
bitmask, and turns on the LED when all capture switches are off.

The new vmaster hook, update_tpacpi_mute_led(), calls the original
vmaster hook, but I forgot to save the original hook function but keep
calling the updated one, which of course results in a stupid endless
loop. Fixed now.

Both patch_realtek.c and patch_conexant.c contain the fairy same code
snippet for supporting Thinkpad ACPI LED controls. Split them into
thinkpad_helper.c and include it from both places. Although this
isn't the best approach from the code size POV, the probability for
coexistence of both Realtek and Conexant codecs on a single machine is
pretty low, thus it'll end up with less memory footprint than
splitting to yet another module.
