video: driver: set RGBA enc session input default color space as BT709 LR

If client fails to configure color aspects to driver, driver does not set
required color space flags to firmware. For RGBA enc session, there is
implicit CSC. Hence, resultant color space should be BT709 LR. But
firmware fails to generate this color space info assuming that color
space info is not required. Hence, fix this by setting BT709 LR as
default color space info for RGBA enc session.
