    kernel/os: Define OS_TICKS_PER_SEC as syscfg
    
    OS_TICKS_PER_SEC was previously defined in mcu specific header.
    Now preprocessor definition is moved to os_time.h and taken
    from syscfg to allow consistent way of changing it.
    
    Severl MCUs already had this configurable in syscfg now
    definition is common for all.
