Lots of changes, sirius support, dt.img generation and updates in qcom mainline

Created by: opendata26

Hey!

Have been working on this for a little while and finally ready for submitting, i have tested this with plasma mobile and weston and it works pretty good.

Quick summary of each patch:

1. Generates a dt.img with qcom kernel, this is needed as to make the bootloader initialize display as cant read the display setting if dtb is appended.
2. removes unused patch that wasn't in kernel sources property
3. updates to use newer kernel along with changing directory name to work with new repository name
4. commit message really explains this one
5. adds support for the z2, currently has: a udev rule to let the touchscreen be recognized as a touchscreen, wifi nvram file for wifi support and x11 and weston subpackages with needed settings and package depends.

If possible could these not be squashed due to their diverse nature please :)
