Add a simplified path evaluation function IMFS_eval_path_devfs() for a device only IMFS configuration. The code size can be further reduced by the application if it disables the support for legacy IO drivers via: #define CONFIGURE_IMFS_DISABLE_MKNOD #define CONFIGURE_IMFS_DISABLE_MKNOD_DEVICE Obsolete CONFIGURE_MAXIMUM_DEVICES. Remove BSP_MAXIMUM_DEVICES. Update #3894. Update #3898.
