lantiq: add Linux 5.4 support as testing kernel version

Switch to the mainline Lantiq PCIe PHY driver and update the vr9.dtsi
accordingly.

The Lantiq IRQ SMP support added upstream required changes to the SoC
dtsi as well.

Following changes are made to the Lantiq kernel patches:

  0005-lantiq_etop-pass-struct-device-to-DMA-API-functions.patch
  0006-MIPS-lantiq-pass-struct-device-to-DMA-API-functions.patch
    applied upstream

  0008-MIPS-lantiq-backport-old-timer-code.patch
    access_ok API update because it lost it's type (which was the first)
    parameter in upstream commit 96d4f267e40f95 ("Remove 'type' argument
    from access_ok() function")

  0024-MIPS-lantiq-autoselect-soc-rev-matching-fw.patch
    merged into 0026-MIPS-lantiq-Add-GPHY-Firmware-loader.patch

  0024-MIPS-lantiq-revert-DSA-switch-driver-PMU-clock-chang.patch
    revert upstream changes required for upstream xrx200 ethernet and
    xrx200 (DSA) switch driver but breaking our driver

  0026-MIPS-lantiq-Add-GPHY-Firmware-loader.patch
    required for our driver but dropped upstream, add former upstream
    version

  0028-NET-lantiq-various-etop-fixes.patch
    now has to use the phy_set_max_speed API instead of modifying
    phydev->supported. Also call ltq_dma_enable_irq() in
    ltq_etop_open() based on upstream commit cc973aecf0b054 ("MIPS:
    lantiq: Do not enable IRQs in dma open")

-Subject: [PATCH] lantiq_etop: pass struct device to DMA API functions
-
-The DMA API generally relies on a struct device to work properly, and
-only barely works without one for legacy reasons.  Pass the easily
-available struct device from the platform_device to remedy this.
-
-Note this driver seems to lack dma_unmap_* calls entirely, but fixing
-that is left for another time.

-The DMA API generally relies on a struct device to work properly, and

-
-Also use GFP_KERNEL instead of GFP_ATOMIC as the gfp_t for the memory
-allocation, as we aren't in interrupt context or under a lock.
-
-Note that this whole function looks somewhat bogus given that we never
-even look at the returned dma address, and the CPHYSADDR magic on
-a returned noncached mapping looks "interesting".  But I'll leave
-that to people more familiar with the code to sort out.

-Add a custom xrx200 ethernet phy compatible to load the firmware matching

-
-We have quite a few boards in the tree were later produced ones are using

++Lantiq XWAY SoC GPHY binding
++============================
++
++This binding describes a software-defined ethernet PHY, provided by the RCU
++module on newer Lantiq XWAY SoCs (xRX200 and newer).
++
++-------------------------------------------------------------------------------
++Required properties:
++- compatible		: Should be one of
++				"lantiq,xrx200-gphy"
++				"lantiq,xrx200a1x-gphy"
++				"lantiq,xrx200a2x-gphy"
++				"lantiq,xrx300-gphy"
++				"lantiq,xrx330-gphy"
++- reg			: Addrress of the GPHY FW load address register
++- resets		: Must reference the RCU GPHY reset bit
++- reset-names		: One entry, value must be "gphy" or optional "gphy2"
++- clocks		: A reference to the (PMU) GPHY clock gate
++
++Optional properties:
++- lantiq,gphy-mode	: GPHY_MODE_GE (default) or GPHY_MODE_FE as defined in
++			  <dt-bindings/mips/lantiq_xway_gphy.h>
++
++
++-------------------------------------------------------------------------------
++Example for the GPHys on the xRX200 SoCs:
++
++#include <dt-bindings/mips/lantiq_rcu_gphy.h>
++	gphy0: gphy@20 {
++		compatible = "lantiq,xrx200a2x-gphy";
++		reg = <0x20 0x4>;
++
++		resets = <&reset0 31 30>, <&reset1 7 7>;
++		reset-names = "gphy", "gphy2";
++		clocks = <&pmu0 XRX200_PMU_GATE_GPHY>;
++		lantiq,gphy-mode = <GPHY_MODE_GE>;
