lantiq: add support for kernel 4.9

The following patches were dropped because they are already applied
upstream:
0012-pinctrl-lantiq-fix-up-pinmux.patch
0013-MTD-lantiq-xway-fix-invalid-operator.patch
0014-MTD-lantiq-xway-the-latched-command-should-be-persis.patch
0015-MTD-lantiq-xway-remove-endless-loop.patch
0016-MTD-lantiq-xway-add-missing-write_buf-and-read_buf-t.patch
0017-MTD-xway-fix-nand-locking.patch
0044-pinctrl-lantiq-introduce-new-dedicated-devicetree-bi.patch
0045-pinctrl-lantiq-Fix-GPIO-Setup-of-GPIO-Port3.patch
0046-pinctrl-lantiq-2-pins-have-the-wrong-mux-list.patch
0047-irq-fixes.patch
0047-mtd-plat-nand-pass-of-node.patch
0060-usb-dwc2-Add-support-for-Lantiq-ARX-and-XRX-SoCs.patch
0120-MIPS-lantiq-add-support-for-device-tree-file-from-bo.patch
0121-MIPS-lantiq-make-it-possible-to-build-in-no-device-t.patch
122-MIPS-store-the-appended-dtb-address-in-a-variable.patch

The PHY driver was reduced to the code adding the LED configuration,
the rest is already upstream:
0023-NET-PHY-adds-driver-for-lantiq-PHY11G.patch

The SPI driver was replaced with the version pending for upstream
inclusion:
New driver:
0090-spi-add-transfer_status-callback.patch
0091-spi-lantiq-ssc-add-support-for-Lantiq-SSC-SPI-controller.patch
Old driver:
0100-spi-add-support-for-Lantiq-SPI-controller.patch
