This patch ensures only minimal level of compatibility necessary to boot
on RK3288 based boards. GPIO and pinctrl interaction, missing in current
implementation, will be improved by own patch in the near future.

Hide unused code under #ifdef notyet (in one case the only caller is under
that same ifdef), or if it is arm (not arm64) specific code under the
__arm__ ifdef to not yield -Wunused-function warnings during the arm64
kernel compile.

The values for tx/rx delays differs accross the different DTS.
Mainline Linux set it to 0x24/0x18
Mostly-Vendor u-boot (the one maintained and developped) to 0x18/0x18
Mostly-Vendor linux (the one maintained and developped) to 0x26/0x11
By experience only 0x18/0x18 works so until the issue is resolved rely on
the bootloader settings.
The property are named {t,r}x_delay and not {t,r}-delay.
The upper bits of the register are a mask of which bits is allowed
to be written, set it otherwise we write nothing.
OF_getencprop returns <0 = for an error.

Add driver for the designware ethernet controller found in some RockChip SoCs.
The driver still rely on a lot of things setup by the bootloader like clocks
and phy mode.
But since netbooting is the only/easiest way to boot rockchip board at the
moment add the driver so other people can test/dev on thoses boards.
