This patch cleans up interface type relevant codes.
Trigger mode is determinded only by i80 mode, which isn't related to Display types - HDMI or Display controller. So this patch makes the trigger mode to be set only in case of i80 mode - For DECON-TV, HW Trigger mode is flaged mandatorily because HDMI Timing Generator generates VSYNC signal which works as a hardware trigger.
Changelog v2. - If interface type is HDMI then set out_type to I80. - fix compile warning.
