Francisco Molina 2e2daae5d0 sys/sema: use sema_ztimer64 to implement old sema api ... This PR removes the old xtimer based implementation for sema. Since this implementation used 64bit timeout, backweard compatibility is kept by having `sema_wait_timed` be implemented by `ztimer64_usec` which is enabled by selecting `sema_deprecated` With this 64bit `sema` api is now deprecated.		2022-03-10 14:19:44 +01:00
