Similar to how it's done for RISC-V, set up the time-slice timer before switching tasks. This ensures that after a
yield_task
, the next task has the full time-slice to run.I've changed the Xtensa tick rate to 30MHz. It doesn't affect much, and it's easier to calculate. We could probably use the original 240MHz but the wifi stack works with 32-bit timestamps and the 17 second range could be a bit too tight.
