zephyr: unify CTX_SAVE handling for Zephyr 

Clean up the ifdefs for ipc_pm_context_save(). By implementing
platform_timer_stop() in the Zephyr wrapper, the original context
save sequence can be used also for Zephyr builds.

By doing this, we can fix issues with IPC timeout on CTX_SAVE.
Disabling all interrupts before the IPC reply is needed also on
Zephyr.
