[PATCH 4/9] OMAP3: HWMOD: fix DSS clock data

The OMAP3 HWMOD data currently contains these errors with DSS clocks:
- dss_rfbi is missing ick opt-clock, which is needed for RFBI to
calculate timings
- dss_dsi is missing ick and sys_clk
- dss_venc is missing dss_96m_fck opt-clock, which is required on
OMAP3430
- dss_venc's interface and main clocks are wrong, causing VENC to fail
to start
These problems were temporarily fixed with a DSS patch
9ede365aa6f74428a1f69c21ca1cf21213167576 ("HACK: OMAP: DSS2: clk hack
for OMAP2/3"), which can be reverted after this patch (and the similar
patches for other OMAPs).
