trxcon/scheduler: refactor description of TRXC_* lchans
Let's avoid fancy alignment in the description of logical channels
for the benefits of having better readability, the ability to add
more comments and fields without making it look ugly.
Also, let's get rid of field 'chan' of 'trx_lchan_desc' structure
since it's not used anywhere, and not actually needed because the
position of each lchan description is defined by its TRXC_* type.
As a bonus, let's add a human readable description to each
lchan definition, so it can be printed in the VTY some day.
