mx6qsabrelite: Remove mx6qsabrelite code in favor of nitrogen6x

mx6qsabrelite and nitrogen6q boards are hardware compatible, so let's avoid the
code duplication and only use the nitrogen6x source code to make board code
maintainance easier.

Tested booting a mainline device tree kernel on a mx6qsabrelite board.
