The IRQ mapping was changed to not being created in the rtc-mt6397
driver, so the irq_dispose_mapping is no longer needed.
Also the dev_id passed to free_irq should be the same as the last
argument passed to request_threaded_irq.
This prevents a "Trying to free already-free IRQ 274" warning when
unbinding the driver.

The Sun4v Hypervisor Core API Specification states:
Time is described by a single unsigned 64-bit word equivalent to a time_t
for the POSIX time(2) system call. The word contains the time since the
Epoch (00:00:00 UTC, January 1, 1970), measured in seconds.

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
