soc: fsl: cpm1: qmc: Introduce functions to change timeslots at runtime

Browse Source 
Introduce qmc_chan_{get,set}_ts_info() function to allow timeslots
modification at runtime.

The modification is provided using qmc_chan_set_ts_info() and will be
applied on next qmc_chan_start().
qmc_chan_set_ts_info() must be called with the channel rx and/or tx
stopped.
