amr: Attempt to unbreak the AMR support in the BSC
The signature of mr_config and the BSC implementation didn't
match and the compiler was warning about it:
osmo_bsc_api.c:530:2: warning: initialization from incompatible pointer type
.mr_config = bsc_mr_config,
^
osmo_bsc_api.c:530:2: warning: (near initialization for ‘bsc_handler.mr_config’)
Change the mr_config again and provide an implementation
that will set the ms and bts data structure. It would be
better to put the size outside of the IE but I am not going
to change it right now. It would also be nice to either move
the AMR setting into the "nitb" structure or have the msc
data be used _after_ the bts settings. This needs to be
cleaned up in the next step.
Manually verified by placing a MO call and checking that
both the channel mode modify and the mode modify request
contain the multi rate config with the rate mr config
(length two bytes, version 1, icmi==1, no start mode being
set).
