This part of the patch doesn't seem right.  As far as I know, AM35xx 
doesn't support the D2D interface.  So it wouldn't make sense to add this 
to the OMAP3-common list.  So instead the patch has been updated here to 
add this to the OMAP34xx and OMAP36xx lists.

Updated patch below.

Subject: [PATCH] ARM: OMAP3: hwmod data: add sad2d hwmod

SAD2D stands for the die to die interface, and is used for communicating
with the optional stacked modem. This hwmod is added in preparation for
the d2d_idle move from pm34xx.c to hwmod data.

[paul at pwsan.com: SAD2D presumably doesn't exist on non-OMAP34xx/OMAP36xx,
 so only add it to the OMAP34xx/OMAP36xx lists]
