ENGR00219837-1 HDMI: Add HDMI_SDMA support for RIGEL TO1.1
In RIGEL TO1.1, the same HDMI_SDMA fix is introduced as ARIK TO1.2. Add
support for RIGEL TO1.1 for HDMI_SDMA functionality.
In this patch:
1.Add hdmi_SDMA_check() interface to judge whether MX6 chip
support HDMI_SDMA.
2.Replace mx6q_version() check with hdmi_SDMA_check() to support
both ARIK To1.2 and RIGEL TO1.1.
