ARM : OMAP: MUSB :Pass board specific data from board file

This patch proposes to pass board specific data for MUSB
(like interface_type, mode etc) from board file by defining
board specific structure.

Each board file can define this structure based on 
its requirement and pass this information to the 
driver.

It addresses a comment from Felipe and thus help
by preventing addition of too many fields in 
musb_platform_data.
