Murali Karicheri 05643e700e samples: drivers: flash_shell: allow run on stm32h745i_disco/stm32h745xx/m4 Now that flash controller driver is supported on M4 of stm32h745i_disco, remove it from platform_exclude list and add an overlay for flash_shell sample.

   Explore a flash device using shell commands.

Overview
********

This is a simple shell module that allows arbitrary boards with flash
driver support to explore the flash device.
