audio_policy: Allow a sample rate of 8 KHz only for VoIP output

Audio library allows only a sample rate of 8 KHz for VoIP output, when
a different sample rate is used, for example 16 KHz, the following
errors occur:
D/AudioHardware7x30(  156): AudioHardware::openOutputStream devices 1
    format 1 channels 1 samplerate 16000
...
E/AudioHardware7x30(156): AudioStreamOutDirect::set return bad values
E/AudioHardware7x30(156):
E/AudioHardware7x30(156): set Failed for AudioStreamOutDirect

After encountering these errors, some apps downgrade to a sample rate of
8 KHz while others stop working.

By removing the sample rate constraint on audio library, it's possible
to use a sample rate of 16 KHz with some apps like Hangouts and Viber,
but other apps like Skype and Line won't work properly anymore.
So it's better to keep the audio library as is and to use a sample rate
of 8 KHz only.
u8800: Adjust Torch brightness.

Reduce the low brightness to 64 since 128 it pretty bright comparing with 255.
Torch overlay is somewhat broken. It gives option to supply low, middle & high
settings, but only takes in two. Nevertheless, add config items for more
brightness options.
u8800: Include Power HAL from LX.

LegacyXperia's Power HAL is optimized for single-core devices.
u8800: Read BT MAC from sysfs.
hwprops: Use correct fields for reading MAC address.
hwprops: Remove NV item reading.

This has been replaced by the kernel. Hwprops now serves the purpose of allowing
users to use custom WLAN/BT MAC addresses.
u8800: Make sure hwprops can write to sysfs.
IDEOSX5Settings: On startup, compare the current state & write new if needed.
u8800: Restart audio_policy.conf with M7630AABBQMLZA40901040.
u8800: Sync init.qcom.fm.sh with upstream.
u8800: Restart media configs with M7630AABBQMLZA40901040.
u8800: Remove 1080p profiles.

MSM7x30 has VIDC with maximum resolution of 720p.
IDEOSX5Settings: Add support to control BT/WLAN MAC addresses.
IDEOSX5Settings: Do not set force mic status on reboot.

The property is set as persist, meaning it will persist over reboot. When user
has enabled this property & reboots the device, the phone greets with a toast
to replug headset. This is not needed.
