ALSA: hda - Increment default stream numbers for AMD HDMI controllers

It turned out that some AMD HDMI controllers still don't provide
proper values in GCAP register (all zero), and the driver assigns only
one stream in that case, although the connected codec chip supports
more than one stream.

In this patch, the default max number of streams for AMD HDMI
controllers is increased to 8, which  should suffice for most use
cases.  The overhead by this increase is more azx_dev struct and BDL
allocations, so it's negligible.  Of course, if the controller
provides a proper GCAP register, the register value would be used.

ALSA: hda - firmware patch code cleanup

Just a code refactoring: the need_codec flag in hda_patch_item struct
can be removed by checking the current mode instead.  No functional
change.

ALSA: hda - Add consistent tag names for firmware patch

Some tags used in the firmware patch file are inconsistent with hwdep
sysfs file names, such as, the firmware patch takes [hint] tag while
sysfs file is */hints.  This makes even me referring back to the
document often.  Let's provide the same tag names as sysfs for
reducing confusions.

ALSA: hda - Correct AD1986A 3stack pin configs

The 3stack pin configs for AD1986A codec had incorrect values that
resulted in broken mic and line-in.

ALSA: hda - Don't create duplicated ctls for loopback paths

AD1986A mic pins (0x1d and 0x1f) share the same widget for controlling
the loopback volume/mute, but the generic parser didn't check it.
This ended up with the duplicated controls for the same effect.

This patch adds the check of the duplication for avoiding it.

After this fix, there will be only one control although it affects
both paths; this remaining issue should be fixed later in a different
patch.

ASoC: bcm: Remove obsoleted Kconfig dependency

CONFIG_SND_SOC_DMAENGINE_PCM was renamed to CONFIG_SND_DMAENGINE_PCM
recently.  And yet we don't have to select it since
CONFIG_SND_GENERIC_DMAENGINE_PCM selects the dependency by itself, so
just rip it off.

ALSA: hda - Split Thinkpad ACPI-related code

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.

Broadwell and Haswell have the same behavior on display audio. So this patch

Broadwell, and apply all Haswell fix-ups to Broadwell.

ALSA: Remove memory reservation code from memalloc helper

Nowadays we have CMA for obtaining the contiguous memory pages
efficiently.  Let's kill the old kludge for reserving the memory pages
for large buffers.  It was rarely useful (only for preserving pages
among module reloading or a little help by an early boot scripting),
used only by a couple of drivers, and yet it gives too much ugliness
than its benefit.
