staging: fbtft: fb_ssd1331: fix mirrored display
When the row scan order is reversed (the default) we also need to reverse the column scan order. This was not done previously, resulting in a mirrored display. Also add support for 180 degree display rotation, in which case simply disable reversed row and column scan order. Tested on an Adafruit 0.96" mini Color OLED display. Signed-off-by: Johannes H.
