Bump Tock kernel version (#374)

* Bump Tock kernel version

* Update boards to new kernel

* Update patches to new kernel

* Update PR template

* Bump libtock-rs

* Use new layout from libtock-rs

* Fix clippy warnings due to updated toolchain

* Fix new toolchain file format

* Bump elf2tab to v0.7.0

* Fix worklow and setup.sh script to use the TOML rust-toolchain file

* New libtock-rs style of declaring the stack.

* Fix padding in layout file.

The layout from libtock-rs generates invalid flash padding.
The value is 32-bit and therefore setting padding to 0xff yields
0xff000000 instead of 0xffffffff that we want.

* adds tock patch for app break hard fault

* sets in deploy, removed patch 04-mpu-fix

* fixed the if deploy

* fixes indentation

* updates board names in install.md

* fix docs and deploy style
