BananaPi M2 Zero: Add HDMI out and ethernet

I'm sending two patches to enable HDMI out and ethernet on the BananaPi M2 Zero. Please let me know whether they can be accepted in the current form, or whether I need to do anything in addition.

Jernej Škrabec found my HDMI out patch, and wrote that seemed good to go. He also let me know that the ethernet patch would probably be rejected, since the BananaPi M2 Zero does not come with a physical RJ-45 port. 
However, it does come with a four-hole dedicated ethernet header. I thought, since the presence of such a header is, as far as I know, enough to enable UART tty, then perhaps the same might go for ethernet? In any 
case, it would be very nice if you can accept the HDMI out patch, and nicer still if you could also accept the ethernet patch!

Kind regards,

Pieter Beers

[PATCH 1/2] ARM: dts: sunxi: h2-plus-bananapi-m2-zero: Add HDMI out

This patch enables the ethernet driver for the BananaPi M2 Zero

The BananaPi M2 Zero does not have an RJ-45 interface, but it
does feature a four-hole header to which an RJ-45 port can be
connected, for a 100 Mbps ethernet link.

I didn't noticed earlier, but BananaPi M2 Zero has mini HDMI, so type should 
be set to "c" here.

Hi, I'm resending my patches that add HDMI out and ethernet to the BananaPi M2 Zero device tree. This time, I put all new nodes in alphabetical order and changed the hdmi connector type to "c" (mini-hdmi).

All the optional features of a board are typically handled by an
overlay.
