mtd: rawnand: micron: Adapt the PAGE READ flow to constraint controllers
There are controllers not able to just read data cycles on the bus. There are controllers not able to do a change column. If we want to support both, we need to check which operation is supported first. This is the exact same mechanism that is in use for parameter page reads (ONFI/JEDEC) as the same problem occurs. Speed testing does not show any throughput penalty so we do not optimize more than that. However it is likely that, in the future, a more robust and exhaustive test will run at boot time to avoid re-checking what is supported and what is not at every call.
