ENGR00223349-4 gpmi: enable the EDO support for mx6q
Enable the EDO mode for mx6q.
The following is the test result with the same nand chip (Micron MT29F32G08QAA)
in mode 4:
The test result without enable the EDO mode:

=================================================
We can see that there is 6 times performance improvement for reading
when we enable the EDO mode.
