rsl: support for ericssons propritary SI13 format
Ericsson has introduced a propritary format to issue the S13 BCCH
information. Normally the system info type field for SI13 would
be encoded as 0x28. Ericsson encodes that field as 0x02 and ads
a bcch mapping parameter, (IEI=F2) This patch sets the BCCH mapping
to 0x00 (=BCCH Normal) statically (0xF200)
The new constands are added to libosmocore, see commit:
