[PATCHv3 3/3] ARM: OMAP4: hwmod_data: add opt clks for dss_hdmi and dss_venc

[Tero Kristo <t-kristo@ti.com>]

These extra optional clocks are required as main clock for these modules
are going to be routed to the main module clock. Otherwise, the hdmi / tv
clocks are not going to be enabled during usage, leading to failure.
