MLK-9920 mtd: qspi: Add ddrsmp parameter to device tree
Since QSPI internal DDR sample point is relevant with board layout,
we can't use same value for all boards. 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.
