video: mcde: Add tripple buffer support
This patch adds tripple buffer support to the mcde
driver. Useful for video mode devices (e.g. HDMI)
where a missed v-sync leads to half frame rate
(the client has to wait for the next v-sync).
Tripple buffering solves this problem since there
are two back buffers the client can use.
Tripple buffering for HDMI is activated in
menuconfig by enabling:
System Type -> Display selection -> Enable tripple
buffer for HDMI display
