This RTC is a 32-bit second counter.
This also solves an issue where mxc_rtc_set_alarm() can return with the
lock taken.

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 mxc_rtc_remove is incorrectly annotated as __exit:
`mxc_rtc_remove' referenced in section `.data' of drivers/rtc/rtc-mxc_v2.o: defined in discarded section `.exit.text' of drivers/rtc/rtc-mxc_v2.o
This should not be done, as devices can be dynamically bound
and unbound to a driver.

devm_ioremap_resource() already checks if the resource is NULL, so
remove the unnecessary platform_get_resource() error check.
