This patch adds sound support for the Hawkboard-L138 system

Signed-off-by: Victor Rodriguez victor.rodriguez@sasken.com --- Notes:

This patch works with da8xx_omapl_defconfig

In order to test ALSA utils select in menuconfig like insmodule:

Sound card support ---> Advanced Linux Sound Architecture ---> ALSA for SoC audio support ---> SoC Audio for the TI DAVINCI chip SoC Audio support for DA850/OMAP-L138 EVM/Hawkboard
