OMAP4: TWL: add vdda_hdmi_dac regulator supply
HDMI requires vdda_hdmi_dac (vdac) power for operation. The regulator,
or the regulator supplying the vdac, has been enabled by default and
things have worked without the HDMI driver enabling the vdac.
I encountered the problem when implementing HDMI device tree support,
where the regulator was not enabled by default.
This patch adds the vdda_hdmi_dac to twl-common.c so that the HDMI
driver can use it.
