MLK-11939: ARM: dts: Add ddrsmp to device tree for i.mx6sx sabreauto and sdb board

Add ddrsmp parameter to device tree for i.MX6SX Sabreauto/Sabresd board.

DDRSMP value:
0 ---- i.MX6SX Sabresd board (RevB and RevA)
2 ---- i.MX6SX Sabreauto board

The Sabresd RevA board also needs to reduce clock to 29Mhz according to
the Spansion spec.
