Beside the quad-read/ddr-quad-read commands, all the commands needed by
this driver is common. If we do not enable the quad-read, this driver
can works with the fast-read mode.

If we use a different NOR which uses different opcodes
(different quad-read opcodes ?), i should add a small patch to fix it. 


I think i should follow Mark's advice to split out the quad-read code.
