Currently, of_match_node compares each given match against all node's
compatible strings with of_device_is_compatible.

To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and also
an alphabetical ordering is more sane there.

Therefore, this patch introduces a function to match each of the node's
compatible strings against all given compatible matches without type and
name first, before checking the next compatible string. This implies
that node's compatibles are ordered from specific to generic while
given matches can be in any order. If we fail to find such a match
entry, then fall-back to the old method in order to keep compatibility.

Because the offload mechanism can fall back to a standard transfer,
having two seperate initialization states is unfortunate. Let's just
have one state which does things consistently. This fixes a bug where
some preparation was missing when the fallback happened. And it makes
the code much easier to follow. To implement this, we put the check
if offload is possible at the top of the offload setup function.

This reverts commit 10535314.
Stephen Chivers reported this is broken as we will get a match
entry '.type = "serial"' instead of the '.compatible = "ns16550"'
in the following scenario:
	serial0: serial@4500 {
		compatible = "fsl,ns16550", "ns16550";
	}

	struct of_device_id of_platform_serial_table[] = {
		{ .compatible = "ns8250",   .data = (void *)PORT_8250, },
		{ .compatible = "ns16450",  .data = (void *)PORT_16450, },
		{ .compatible = "ns16550a", .data = (void *)PORT_16550A, },
		{ .compatible = "ns16550",  .data = (void *)PORT_16550, },

		...
		{ .type = "serial",         .data = (void *)PORT_UNKNOWN, },
		{ /* end of list */ },
	};

So just revert this patch, we will use another implementation to find
the best compatible match in a follow-on patch.

    2. NETDEV events
    3. INET or INET6 events

On the one hand, the invocation of netdev_master_upper_dev_get()

Make sure that for Ethernet ports, the port GID table index 0 is always
occupied with a default GID of the relevant IPv6 link-local adderss.

This provides better user experience for legacy applications that don't use
the RDMA CM and were working on index 0 prior to the IP addressing change.

Also, as GIDs are generated from IP addresses of the network devices that
are associated with the port, it's basically possible that the GID table
will be empty if no IP address was assigned.  This doesn't comply with the
IB spec section 4.1.1 "GID usage and properties".
