Qualcomm driver updates for v6.15

Improve the client interface for the Qualcomm ICE driver to avoid
leaking references, including fixing the client drivers to call the new
function.

Adopt str_on_off() helper in AOSS driver and mark non-global servreg QMI
element info array in the PDR driver static.
