rn5t567: do not register poweroff
The Colibri iMX7 uses the SNVS_PMIC_ON_REQ signal (connected to the
PMIC's PMIC_ON_EXTIN GPIO) to power off the module. The SNVS RTC
driver provides a poweroff callback which causes that signal to
go low. However, the current PMIC driver registers a poweroff
callback earlier and therefor the kernel uses the PMIC poweroff
instead of the SNVS RTC poweroff callback.
