userspce/wrsw_hal: share IPC structures with the RT CPU header, added ptracker enable/disable rts call and ptpd interface for it (HALEXP_LOCK_CMD_ENABLE_TRACKING)

userspace/wrsw_hal/hal_exports.c: convert from nanoseconds to clock cycles using REF_CLOCK_PERIOD_PS

userspace/wrsw_hal: halexp_query_ports() now reports also number of physical ports supported in the fw, reduced HAL_MAX_PORTS to avoid mini-ipc buffer overflow
