it compatible with Linux' naming.

Add helpers ofnode_read_phy_mode() and dev_read_phy_mode() to parse the
"phy-mode" / "phy-connection-type" property. Add corresponding UT test.

Use them treewide.

This allows us to inline the phy_get_interface_by_name() into
ofnode_read_phy_mode(), since the former is not used anymore.

Add helpers ofnode_get_phy_node() and dev_get_phy_node() and use it in
net/mdio-uclass.c function dm_eth_connect_phy_handle(). Also add
corresponding UT test.

This is useful because other part's of U-Boot may want to get PHY ofnode
without connecting a PHY.

At present we support reading a string list a string at a time. Apart
from being inefficient, this makes it impossible to separate reading of
the devicetree into the of_to_plat() method where it belongs, since any
code which needs access to the string must read it from the devicetree.

Add a function which returns the string property as an array of pointers
to the strings, which is easily used by clients.

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

Re-send because of line-wraps.

Without this patch, u-boot just hangs if the fdt pointer is
not initialized. The diagnostic subsystems are not yet initialized,
so all you get is a blind hang.

At present if these calls are used with of-platdata, a confusing error is
produced, referring to a function not actually called by the code causing
the problem.

Fix this by not inlining, so that the error mentions the dev_read_...()
function and it is more obvious what is going on.
