This adds basic support for the Tegra2 USB controller. Board files should
call board_usb_init() to set things up.

Configuration is performed through the FDT, with aliases used to set the
order of the ports, like this fragment:

        aliases {
		/* This defines the order of our USB ports */
                usb0 = "/usb@0xc5008000";
                usb1 = "/usb@0xc5000000";
        };

It's derived from ehci-mxc and uses the header files of the
ehci-fsl interface. The callback board_ehci_hcd_init() has
been introduced to allow for board-specific setup when USB
is started.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
