Note: SCART0 & SCART1 are legacy features. They were
used to generate 0/6/12 signal on an ext. A/V bd. However,
most TV/Audio sets have their own Scart control ic & hence
these 2 pins have alternate functions via optional jumpers.
SCART1 shares with I2C_INT & GND; SCART0 pin shares
with SLOT_IN_DETECT.
