Subject: [V1] rtc:rtc-vr41xx :- Retunr error is not correct in rtc_probe

Here, rtc_probe is returning EBUSY at any error case.
It should return ENOMEM insted of EBUSY.

-EBUSY A resource you need is not avaialable.

-ENOMEM This is used to signify lack of memory resources.

-ENODEV This is used when no device is available.
