broadband-modem-mbim: refine access technology updates

Browse Source 
This patch refines the access technology updates on a MBIM modem by
observing the MBIM_CID_PACKET_SERVICE notifications in addition to the
MBIM_CID_REGISTER_STATE notifications. If a MBIM_CID_PACKET_SERVICE
notification indicates the highest available data class, the current
access technology is updated to reflect that. Otherwise, the access
technology is updated according to the available data classes indicated
by a MBIM_CID_REGISTER_STATE notification.
