lantiq: Add support for linux 4.4

The following patches were dropped because they are already applied
upstream:
- 0038-MIPS-lantiq-fpi-on-ar9.patch
- 0039-MIPS-lantiq-initialize-usb-on-boot.patch
- 0042-USB-DWC2-big-endian-support.patch
- 0043-gpio-stp-xway-fix-phy-mask.patch

All other patches were simply refreshed, except the following:
- 0001-MIPS-lantiq-add-pcie-driver.patch
  Changes to arch/mips/lantiq/xway/sysctrl.c (these changes disabled
  some PMU gates for the vrx200 / VR9 SoCs) were removed since the
  upstream kernel disables unused PMU gates automatically (since
  95135bfa7ead1becc2879230f72583dde2b71a0c
  "MIPS: Lantiq: Deactivate most of the devices by default").
- 0025-NET-MIPS-lantiq-adds-xrx200-net.patch
  Since OpenWrt commit 55ba20afcc2fe785146316e5be2c2473cb329885 drivers
  should use of_get_mac_address(). of_get_mac_address_mtd is not
  available for drivers anymore since it's called automatically within
  of_get_mac_address().
- 0028-NET-lantiq-various-etop-fixes.patch
  Same changes as in 0025-NET-MIPS-lantiq-adds-xrx200-net.patch

While refreshing the kernel configuration SPI support had to be moved to
config-4.4 because otherwise M25P80 was disabled.
