i3c: mipi-i3c-hci: Resume controller explicitly

On an HW I'm using in enabling work the RESUME bit is not set in the
HC_CONTROLLER register when Host Controller goes to halt state. Value 1
should mean controller is suspended when reading and writing 1 resumes it.

Because of this erratic behaviour plain HC_CONTROL read and write back
won't resume the controller. Therefore do it by setting the RESUME bit
explicitly.
