tinyalsa fails to retrieve the correct value for the period count
from the f_audio_source driver and tries to use zero instead.
This wasn't a problem before because the usb audio HAL used hard coded values
that were compatible with the driver.

1. Fix the HAL version check
2. Disable some test temporarily as the deprecated tags were used.

Do not read the ALSA PCM device configuration when playback
or capture is active.
Do not force ALSA profile update if card and device passed
to out/in_set_parameters() do not change.
Hold the main HAL lock when closing or opening the
ALSA PCM device.

Agreement with MHL consortium mandates that the open source implementation
should mention only RAP/RCP/Scratchpad command and their related constant
definitions.

Also added a new event definition that provides with the capability info
of the connected device.

The number of channels can be "forced" using k_force_channels.
If the channel count proposed by AudioFlinger is not permitted
by the device, it is emulated.

This HAL was intended to support doze mode but it is currently
unused and it's best for it to stay that way.

Pass device address (and audio source for inputs) to
open_output_stream() and open_input_stream() audio HAL functions.

This reverts commit 0e956a7cd2dee76b762320c141960ffdb64d24eb.

The decision was to revert to the old behavior where retransmission
will be handled by HAL for efficiency.
