mobile: Keep track of cell channel description during dedicated mode
The initial cell channel decription is received via SI1. During a call this
description may change due to handover, assignment, frequency redefinition.
Whenever it changes, the last received cell channel description is used to
handle messages that do not include this information element.
Example of one call with handover inbetween. The assignments do not include
a cell channel description:
IMMEDIATE ASSIGNMENT: Use cell channel description from SI1.
ASSIGNMENT COMMAND: Re-use cell channel description from SI1.
HANDOVER COMMAND: Use new cell channel description from HANDOVER COMMAND.
ASSIGNMENT COMMAND: Re-use cell channel description from HANDOVER COMMAND.
