Update flash drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

Disable this option only if you want to simulate

a specific FLASH interface that requires aligned read access.

If selected, writing to a non-erased program unit will succeed, otherwise, it will return an error.

Keep in mind that write operations can only pull bits to zero, regardless.

Only up to this number of beginning pages will be tracked
|
|
while catching dedicated flash operations and thresholds.
|
|
This number is not automatic because implementation uses
|
|
UNTIL_REPEAT() macro, which is limited to take explicitly
|
|
number of iterations.
|
|
This is why it's not possible to calculate the number of pages with
|
|
preprocessor using DT properties.
