[PATCH] device property: constify fwnode_get_phy_mode() argument

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

fwnode_get_phy_mode() does not modify the fwnode argument, merely
using it to obtain the phy-mode property value. Therefore, it can
be made const.

Patch generated against net-next tree as that was where it was used and
tested.
