Nexus 4: b81

It's been awhile since the last N4 build. But to be honest this kernel almost has everything needed and only one issue left: The wakup delay on calls. I have to think about some ways to get rid of it in the future. I've lowered the temperature threshold to 70°C and added a few commits from the N5 m-branch. Its also built with an updated toolchain.

Changelog:
-temp threshold set to 70°C
-few commits from M
-updated toolchain
