Subject: [PATCH 2/2] tty: serial: qcom-geni-serial: Implement start_rx callback

In suspend sequence stop_rx will be performed only if implementation for
start_rx callback is present.

Set qcom_geni_serial_start_rx as callback for start_rx so that stop_rx is
performed.

I think you also want a Fixes tag here, right? ...because if only the
first patch is taken then it can actually regress Qualcomm devices.
Thus:

Fixes: c9d2325cdb92 ("serial: core: Do stop_rx in suspend path for
console if console_suspend is disabled")
