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>

Enable partial erase feature. Partial erase is performed in time
|
|
slices instead of blocking MCU, for the time it is needed to
|
|
complete operation over given area.
|
|
This allows interrupting flash erase between operations
|
|
to perform other task by MCU.
|
|
This feature may also be used for better syncing flash erase
|
|
operations, when compiled with SOC_FLASH_NRF_RADIO_SYNC_TICKER,
|

with Bluetooth.
