spi-memdrv.c does not implement open() or close(), which means
`null_handler_open()` is called, but `errno` is never set:
``` open.c:
if ( iop != NULL ) {
rv = do_open( iop, path, oflag, mode );
} else {
errno = ENFILE;
rv = -1;
}
va_end( ap );
return rv;
```
Is the expectation that I should update `spi_flash_m25p40_ro_driver_descriptor`
with handlers for open and close before passing it to
`rtems_libi2c_register_drv()`? Am I not initializing some part of a framework
that should add those handlers?
