Patrice Chotard 38f7d3b653 cmd: bind: Fix driver binding on a device
Fix a regression brings by commit 84f8e36f03 ("cmd: bind: allow to
bind driver with driver data")

As example, the following bind command doesn't work:

   bind /soc/usb-otg@49000000 usb_ether

As usb_ether driver has no compatible string, it can't be find by
lists_bind_fdt(). In bind_by_node_path(), which called lists_bind_fdt(),
the driver entry is known, pass it to lists_bind_fdt() to force the driver
entry selection.

For this, add a new parameter struct *driver to lists_bind_fdt().
Fix also all lists_bind_fdt() callers.

Fixes: 84f8e36f03 ("cmd: bind: allow to bind driver with driver data")
