The ftm_rtc_driver has been registered while module init, however there
is not unregister step for module exit, now use the macro
module_platform_driver replace device_initcall, which can register and
unregister platform driver automatically.

rtc_register_device() is a managed interface but it doesn't use devres
by itself - instead it marks an rtc_device as "registered" and the devres
callback for devm_rtc_allocate_device() takes care of resource release.
This doesn't correspond with the design behind devres where managed
structures should not be aware of being managed. The correct solution
here is to register a separate devres callback for unregistering the
device.
While at it: rename rtc_register_device() to devm_rtc_register_device()
and add it to the list of managed interfaces in devres.rst. This way we
can avoid any potential confusion of driver developers who may expect
there to exist a corresponding unregister function.

Original device id would conflict with crypto driver, change it.

Use dev_pm_set_wake_irq() instead of flag IRQF_NO_SUSPEND to enable

The function “platform_get_irq” can log an error already.
Thus omit redundant messages for the exception handling in the
calling functions.
This issue was detected by using the Coccinelle software.

For the platforms including LS1012A, LS1021A, LS1028A, LS1043A,
LS1046A, LS1088A, LS208xA that has the FlexTimer
module, implementing alarm functions within RTC subsystem
to wakeup the system when system going to sleep (work with RCPM driver).
