[PATCH 2/2 RESEND] rtc: rtc-hid-sensor-time: enable HID input processing early

[Alexander Holler]

Enable the processing of HID input records before the RTC will be registered,
in order to allow the RTC register function to read clock. Without doing
that the clock can only be read after the probe function has finished.
