Pausing audio playback is not an illegal state so it doesn't
seem sensible for poll() to return -EBADFD on a paused stream.
There's also no reason to assume that we can't write more data
to the DSP while playback is paused. Remove the -EBADFD so that
a stream in paused state will still report the buffer
availability from poll(). It is up to the user process to
manage its state so that it knows whether it is paused or not.

According to the HDA specification the baseline ELD length is counted in
DW of 4 bytes instead of in bytes.
Fix the code accordingly.
Baseline length is not used by the kernel so only the ELD exported to
userspace was affected. No issues have been reported.
v2: Fixed so that eld_size is adjusted upwards accordingly as well.

The ATI/AMD video/audio latencies are specified in apparent HDMI VSDB
format. In this format values above 251 are not valid (or stream
component is not supported - 255), but no checking is performed since
this was not mentioned in the AMD HDA verbs specification.
Check that the latencies are valid before using them, and add a comment
describing the formats.

Add error checks to HBR status reads (both generic and ATI/AMD) and
ATI/AMD codec reads for ELD generation.
Unchecked errors in these just caused more errors later on (invalid
codec writes for the HBR ones and ELD parsing errors for the ATI/AMD ELD
ones), but it is better to catch them earlier.

According to USB Audio spec v2 bits 25 and 26 of bmChannelConfig are
"Back Left of Center - BLC" and "Back Right of Center - BRC",
respectively.
They are currently assigned to ALSA channels BLC/BRC. However, the ALSA
BLC/BRC are actually the rather nonsensical "bottom left center" and
"bottom right center", so the channels will be assigned wrongly. The
comments in the USB code are also similarly wrong, so this is not
readily apparent without looking at the actual specification.
Fix the channel mapping by mapping bits 25 and 26 to RLC (Rear Left
Center) and RRC (Rear Right Center), respectively, instead.

Channel map positions FLH, FCH, FRH duplicate positions TFL, TFC, TFR.
Both are the speakers above the front speakers (CEA uses "high" and USB
audio uses "top" nomenclature).
Since the USB audio code has used the TFx positions since v3.8
(04324ccc75, "ALSA: usb-audio: add channel map support") but the HDMI
code only just started using FxH in a5b7d510b2 ("ALSA: hda -
hdmi: Fix channel maps with less common speakers") which is not yet in
any released kernel, standardize on TFx instead.

The SPDIF output MBP11,2 requires the pin control to be set/cleared
for turning on/off the optical SPDIF. The red light turns off only
when the corresponding pin control is cleared (or powered to D3).

The commit [8fe7b65ab4: ALSA: hda - Apply GPIO setup for MacBooks
with CS4208] added a fixup entry matching with the vendor id 0x106b.
This broke the fixups for previous MBA6,1 and 6,2, since the PCI SSID
vendor id matches before evaluating the codec SSIDs.
We had a similar issue on Mac with Sigmatel codecs, and solve this
problem again similarly, by introducing a skeleton entry matching with
the all MacBooks, then remap to the right one.
