[U-Boot] [PATCH v2 5/5] arm: omap3: Add HEAD acoustics (HA) board variant omap3_ha to tao3530

[Stefan Roese]

The Head acoustics (HA) baseboard used the Technexion TAO3530 SOM
and has only some minor differences to the Technexion Thunder baseboard.
This patch adds support for this HA baseboard / TAO3530 as the "omap3_ha"
build target.
