[PATCH] MUSB: Set INDEX register to 0 before accessing CONFIGDATA

["Gadiyar, Anand" <gadiyar@xxxxxx>]

From: Anand Gadiyar <gadiyar@xxxxxx>

The Index register needs to be zero to access CONFIGDATA.
musb_ep_select()will not set the MUSB_INDEX register unless INDEXED
mode addressing is used. This change will set the register correctly
in INDEXED as well as FLAT mode.
