[PATCH 2/2] ARM: OMAP4: DSS hwmods: Add OCPIF_SWSUP_IDLE to all DSS L3 slave interfaces

[archit@ti.com (Archit Taneja)]

The clock for all DSS L3 slave interfaces had been recently changed to
"dss_fck" from "l3_div_ck". "dss_fck" is an optional clock in DSS clock domain
which can't autoidle when enabled.

Add OCPIF_SWSUP_IDLE flag to all the L3 slave interfaces used by DSS hwmods so
that clock is explicitly enabled and disabled by software. Without this,
"dss_fck" would be left as enabled and the OMAP4 device won't idle even when
DSS is not in use.
