Enable arm64 functionality on your L009!

Usually, when a device is built on arm32 architecture, it is not possible to switch to arm64 due to hardware limitations, but this is an exception! The L009UiGS and L009UiGS-2HaxD-IN devices come with an arm64 processor that was initially run in arm32 mode for stability, but we have improved our software! Now, it is possible to do a simple package switch.
