OMAP4: DSS2: HDMI: Add DSS feature for CTS calculation

CTS and N parameters are used to regenerate the audio clock from
the TMDS clock at the HDMI sink. In  OMAP4430 ES1.0 version
the calculation of the CTS parameter is done by the HDMI IP
(hardware mode) while in others it must be done by the HDMI driver
(software mode). A DSS feature is used to indicate the HDMI
driver which mode is used.
