create_pending_snapshot() will go readonly on _any_ error return from

just making a snapshot and asking it to inherit from an invalid qgroup. For
example:

The existing TLV callback implementation copies all of the
cea_channel_speaker_allocation map table to the TLV container
irrespective of what is reported by sink. This is of little use
to the userspace application.
With this patch, it parses the spk_alloc block as queried from
the ELD, and copies only the corresponding mapping channel
allocation entries from the cea channel speaker allocation table.
Thus the user can parse the TLV container to identify sink's
capability and set the channel map accordingly.
It shouldn't impact the behavior in AMD chipset, as this makes
use of already parsed spk alloc block to calculate the channel
map.

Whenever htt rx indication i.e target to host messages are received
on rx copy engine (CE5), the message will be freed after processing
the response. Then CE 5 will be refilled with new descriptors at
post rx processing. This memory alloc and free operations can be avoided
by reusing the same descriptors.
During CE pipe allocation, full ring is not initialized i.e n-1 entries
are filled up. So for CE 5 full ring should be filled up to reuse
descriptors. Moreover CE 5 write index will be updated in single shot
instead of incremental access. This could avoid multiple pci_write and
ce_ring access. From experiments, It improves CPU usage by ~3% in IPQ4019

In order to implement pin control for Baytrail, we need data
structures in which to store and pass along pin, group, function,
community and SOC data information.
Baytrail has 3 GPIO controllers. Add SCORE, NCORE and SUS
controller data:
- pins (for all controllers),
- pad map for pins (for all controllers; we need this since pads
are not ordered),
- groups (for SCORE and SUS controllers),
- functions (for SCORE and SUS controllers),
- communities (for all controllers),
- soc specific data gathering all of the above and the ACPI UID
(for all controllers)
This information is useful for pin control functionality.
NCORE data is lighter than the other two controllers' due to
lack of pin documentation in the public datasheet.
