The flash shell can now build when there isn't a chosen zephyr,flash-controller available, so we can simplify the filter to apply this sample to more boards. Two STM32 H7 board configurations are excluded because the flash driver isn't supported yet on the M4 core. Signed-off-by: Maureen Helm <maureen.helm@nxp.com>

Flash Shell Sample
##################
Overview
********
This is a simple shell module that allows arbitrary boards with flash
driver support to explore the flash device.
Building and Running
********************
This project can be built and executed on as follows:
.. zephyr-app-commands::
:zephyr-app: samples/drivers/flash_shell
:host-os: unix
