Initial bringup for i_lgu (lu6200).

Fixup lge/lge_board/i_lgu to compile and run.

Merge cm-10.1 changes into lge/lge_board/i_lgu.

Add initial cyanogenmod config.

Issues:

* Audio path is not perfect.  Bluetooth audio is reported "very quiet".

* Using BCMDHD_B1 for now, as it works.  Investigate using BCMDHD_B2.
