[PATCH v4 0/2] arm64: Add basic support for Kobol's Helios64

Hello,

in v3 Johan still found some inconsistencies in how I sorted (or didn't
sort) the device tree properties. The rules I applied now are:

at the beginning of a node: compatible, reg and interrupt stuff
status and #* at the end
i2c-scl-rising-time-ns before i2c-scl-falling-time-ns
regulator-name first among regulator-*
regulator-min-microvolt before regulator-max-microvolt
pinctrl-names before pinctrl-0
tx_delay grouped with (and after) rx_delay
vcc12* after vcc5*
otherwise alphabetically

other things changed are:

- drop disable-wp and supports-emmc for emmc
- use led-0 and led-1 as node names for the leds
- rename pinctrl for the leds according to the line name in the schematic
- drop linux,default-trigger = "none";
- add an enable gpio for the sd regulator
- some whitespace nits

While testing I rebased to 5.9 and for an unknown reason this kernel
fails to boot (just no output), but the resulting dtb works just fine
with a Debian 5.8 kernel.
