clocksource: sti: Provide support for the ST LPC Clocksource IP
This IP is shared with Watchdog and RTC functionality. All 3 of
these devices are mutually exclusive from one another i.e. Only 1
IP can be used at any given time. We use the device-driver model
combined with a DT 'mode' property to enforce this.
The ST LPC Clocksource IP can be used as the system (tick) timer.
