i3c: mipi-i3c-hci: Factor out reset-and-restore helper

Browse Source 
Factor the reset-and-restore sequence out of i3c_hci_rpm_resume() into
a separate helper.

This allows the same logic to be reused for recovery paths in subsequent
changes without duplicating suspend/resume handling.

No functional change.
