[OpenWrt-Devel,4/4] a71xx: add support for TP-Link RE450

Add full support for TP-Link RE450.
The wireless SoC is similiar to Archer C7: QCA9558 + QCA9880 (pci).
The ethernet interface is AR8035, but the mdio is connected to the gpio and
the chipset builtin mdio bus isn't used, which is unique (and weird), so the
kernel gpio mdio module is used.
The two ethernet leds are connected to the GPIO, so they are both configured,
one to indicate link status and the other to indicate data transfer.

The generation of the image was added to the image Makefile.
The return value of tplink-safeloader is not ignored anymore (to fail on error)

The result factory image is flashable from the stock web ui.

Hi,

again lots of changes all thrown into one patch.

changes like
> -define Image/Build/TPLINK-SAFELOADER
> +define Image/Build/TPLINK-SAFELOADER-ELF

need to be in their own patch.

and the following
> +# mktplinkfw-kernel <kernel-file> <output-file> <hw-id>
> +define Build/mktplinkfw-kernel
> +	$(STAGING_DIR_HOST)/bin/mktplinkfw-kernel \

> +		-L $(KERNEL_LOADADDR) -E $(KERNEL_LOADADDR) \
> +		-k $1 \
> +		-o $2
> +endef

should be part of the patch adding the tool rather than the board patch.
it might even qualify for its own patch.

	John
