status="ok" treated as disabled by DM

[Roger Quadros]

Hi,

If the device tree node has status="ok" then the u-boot DM will treat the device as disabled.
There are still quite many devices using "ok" instead of "okay" or no status and those devices will not be bound.

What is the right fix?
1) make u-boot DM to treat satus="ok" as enabled.
2) fix device tree by changing "ok" to "okay".

cheers,
