[PATCHv7,09/12] ARM: OMAP4: hwmod data: temporarily comment out data for the sl2if IP block

Commit Message

The OMAP4 sl2if IP block requires some special programming for it to
enter idle. Without this programming, they will prevent the rest of
the chip from entering full chip idle.

This patch comments out the IP block data.

Later, once the appropriate support is available, this patch can be
reverted.

Originally I was hoping that we could apply a real fix for this one.  But 
looking at the proposed alternative in the old SL2IF E-mail threads, I'm 
still not convinced by what's proposed there.  So we'd better take this 
one for the time being.

Queued for 3.6-rc.
