Devicetree/PPC: fix devicetree's fixup ...

Currently Barebox fails to boot a kernel/devicetree pair on PowerPC.

With of_find_node_by_path() the framework uses a global variable to find
the root node and fails. With of_find_node_by_path_from() and forwarding
the 'root' parameter it works again as expected.

This fixes the following error message at run-time:

Loading U-Boot uImage '/tmp/tftpcmd/kernel'
Loading devicetree from '/tmp/tftpcmd/oftree'
bootm: No devicetree given.
handler failed with: Invalid argument

    net: Allow to use multiple network interfaces at once

changes the eth_send() function:

-       return eth_current->send(eth_current, packet, length);
+       return edev->send(eth_current, packet, length);

But we have to change the both eth_current occurrences to edev here!

ARM: omap: xload: Fix func uninitialized warning ...

When doing USB boot without having it enabled in the config func is used
unitialized. Explicitly set this to NULL so that booting fails in this case.

Build with -fno-delete-null-pointer-checks ...

This becomes important with gcc-4.9. Without this gcc assumes
that accessing NULL pointers traps and everything that happens
behind the access is not executed. This recently happened with
i.MX53 which has:

static int imx53_silicon_revision(void)
{
	void __iomem *rom = MX53_IROM_BASE_ADDR;

	rev = readl(rom + SI_REV);
	...
}

This resulted in object code in which the last instruction is
the readl, the reset of the function is missing because gcc assumes this
is never executed.

Disable this optimization with -fno-delete-null-pointer-checks since
in barebox NULL pointers can indeed be valid.
