rtc: st: Add new driver for ST's LPC RTC ST's Low Power Controller (LPC) controls two devices; watchdog and RTC. Only one of the devices can be used at any one time. This is enforced by the correlating MFD driver. This portion of the driver-set controls the Real Time Clock.

rtc: st: Update IP layout information to include Clocksource Initial submission adding support for this IP only included Watchdog and the Real-Time Clock. Now the third (and final) device is enabled this trivial patch is required to update the comment in the RTC driver to encompass Clocksource.

rtc: st-lpc: fix possible race condition The IRQ is requested before the struct rtc is allocated and registered, but this struct is used in the IRQ handler. This may lead to a NULL pointer dereference. Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc before requesting the IRQ.
