apple-iphone7: new device (Apple iPhone 7/7+) (MR 2289)

Downstream kernel made by Corellium which enables the iPhone 7 to boot.

This is the continuation of my work for a PostmarketOS port based on
@MartijnBraam kernel and devices packages.

PogoOS by the Checkra1n team is used to boot the Linux kernel. Further
instructions will be available in the PostmarketOS Wiki page.
