hal: move audio specific config files to HAL 

-Move all audio specific config files from device/qcom/msm8xxx
to hardware/qcom/audio/configs/msm8xxx folder for
msm8916_32, msm8916_64 and msm8909 targets
-audio: configs: add target specific audio policy configuration XML.
Add target specific audio policy configuration XML file for all targets
with enhancements such as additional formats under compressed_offload
output, new device ports such as proxy, line, fm etc., new outputs like
direct_pcm, raw etc. as per the text based audio_policy.conf file and
enable its usage by setting the flag USE_XML_AUDIO_POLICY_CONF to 1.

    <!-- Modules section:

        There is one section per audio HW module present on the platform.

        Each module section will contains two mandatory tags for audio HAL “halVersion” and “name”.

        The module names are the same as in current .conf file:

                “primary”, “A2DP”, “remote_submix”, “USB”

        Each module will contain the following sections:

        “devicePorts”: a list of device descriptors for all input and output devices accessible via this

        module.

        This contains both permanently attached devices and removable devices.

        “mixPorts”: listing all output and input streams exposed by the audio HAL

        “routes”: list of possible connections between input and output devices or between stream and

        devices.

            "route": is defined by an attribute:

                -"type": <mux|mix> means all sources are mutual exclusive (mux) or can be mixed (mix)

                -"sink": the sink involved in this route

                -"sources": all the sources than can be connected to the sink via vis route

        “attachedDevices”: permanently attached devices.

        The attachedDevices section is a list of devices names. The names correspond to device names

        defined in <devicePorts> section.

        “defaultOutputDevice”: device to be used by default when no policy rule applies

# The "primary" module is mandatory and must include at least one output with

# AUDIO_OUTPUT_FLAG_PRIMARY flag.

# Each module descriptor contains one or more output profile descriptors and zero or more

# input profile descriptors. Each profile lists all the parameters supported by a given output

# or input stream category.

# The "channel_masks", "formats", "devices" and "flags" are specified using strings corresponding

# to enums in audio.h and audio_policy.h. They are concatenated by use of "|" without space or "\n".
