Tatenda Chipeperekwa 319eec11d9 hwc: Add support for frame rate change on HDMI devices 
When an HDMI display is connected, we report all the available
configurations to the framework by translating the EDID data.

This information can be queried, and subsequently used to change
the frame rate of the HDMI display.

Note: this change does not provide support for changing the resolution
of the HDMI display.
