samples: dts: Extend nucleo_h743 DTS to support attached QSPI memory

The nucleo_h743 allows extra capes to extend its functionality.

In our case it has been extended to use 32MiB SPI-NOR memory
connected to QUADSPI dedicated pins from block2.

Moreover, upper 16MiB of SPI-NOR memory has been used to store
littlefs data to test 4B addressing mode (which may cause problems
when NOR-flash is larger than 16 MiB).

Now the littlefs sample can be used to test this extension:
west build -p always -b nucleo_h743zi ./zephyr/samples/subsys/fs/littlefs
