HaiLong Yang ebc4a37a21 samples: flash_shell: add support for gd32 boards After add zephyr,flash-controller property, most gd32 boards support flash_shell sample. gd32vf103c_starter and gd32vf103v_eval only have 32KB SRAM, so we should reduce CONFIG_HEAP_MEM_POOL_SIZE to 8KB. gd32f350r_eval only have 16KB driver, exclude from flash_shell sample.

Flash Shell Sample
##################

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