Many drivers are defining a DRV_VERSION. This is often only used for
MODULE_VERSION and sometimes to print an info message at probe time. This
is kind of pointless as they are all versionned with the kernel anyway.
Also the core will print a message when a new rtc is found.

IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there
is no need to do that again from its callers. Drop it.
gemini driver was using likely() for a failure case while the rtc driver
is getting registered. That looks wrong and it should really be
unlikely. But because we are killing all the unlikely() flags, lets kill
that too.

Use resource_size function on resource object instead of explicit
computation.
No need to set .owner here. The core will do it.
Remove .owner field if calls are used which set it automatically
