Patryk Duda 8a85f0e87f drivers: flash: Introduce API function for flash extended operations 
Besides of standard flash operations like write or erase, flash
controllers also support additional features like write protection or
readout protection. These features are not available in every flash
controller, what's more controllers can implement it in a different way.

It doesn't make sense to add a separate flash API function for every
flash controller feature, because it could be unique (supported on small
number of flash controllers) or the API won't be able to represent the
same feature on every flash controller.

Extended operation interface provides flexible way for supporting flash
controller features. Code space is divided equally into Zephyr codes
(MSb == 0) and vendor codes (MSb == 1). This way we can easily add
extended operations to the drivers without cluttering the API or
problems with API incompatibility. Extended operation can be promoted
from vendor codes to Zephyr codes if the feature is available in most
flash controllers and can be represented in the same way.
