FIX: Fix scheduler for the task switch, separate desktop and mobile
targets.
- Giving priority to aarch64 support.
- The scheduler needed those fixes before proceeding to aarch64
support.
- We use the register approach, which is correct here, the
platform code will just take those records and execute them.
