Subject: [Patch v1] rtc: fix for the DA9052 rtc device registration

DA9052/53 MFD core handles only virtual irq therefore rtc driver needs
to be updated to work on virtual irq. Without this update DA9052/53 rtc 
driver will fail during its registration.
Also getting irq by it name is no longer supported in DA9052/53 core.
