zephyr: Enable fatfs.
Enables the fatfs filesystem in the zephyr port.
Example usage with an SD card on the mimxrt1050_evk board:
import zephyr, os
bdev = zephyr.DiskAccess('SDHC')
os.VfsFat.mkfs(bdev)
os.mount(bdev, '/sd')
with open('/sd/hello.txt','w') as f:
f.write('Hello world')
print(open('/sd/hello.txt').read())
