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.

The LPC RTC supports dates way beyond 2038, don't limit it artificially as
the kernel handles dates after 2038 properly.

Make driver use u64 variables and functions to be sure that
it will support dates after year 2038.

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.

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.
