ARM: OMAP2+: hwmod: Add USB hwmod data for AM437x.

Commit Message

George Cherian Oct. 14, 2013, 12:36 p.m. UTC

Add hwmod for USBSS and the OCP2SCP for AM437x.
AM437x has got 2 instances of USBSS.

Signed-off-by: George Cherian <[e-mail]>

This was tested on AM437x EPOS EVM with Afzal's v6 of AM43x PRCM basic support 
and Tero's DT clock Series
