The selection of the Cortex M systick driver to be used as a system clock driver is controlled by CONFIG_CORTEX_M_SYSTICK. To replace it by another driver CONFIG_CORTEX_M_SYSTICK must be set to 'n'. Unfortunately this also controls the interrupt vector for the systick interrupt. It is now routed to __reserved. More bad the interrupt vector can not be set by IRQ_CONNECT as it is one of the hard coded interrupts in the interrupt table. Route the hard coded systick interrupt to z_clock_isr and make z_clock_isr a weak symbol that can be overwritten by an alternative systick system clock driver.
