Remove note on PCCCH/PBCCH support because according to 3GPP TS 44.060
version 12.5.0 Release 12 § 1.6 "The network shall never enable PBCCH
and PCCCH".
The rationale behind this from GP-091955:
"Due to that P-channels are not deployed by any operator and are not
expected ever to be, it has decided to remove the requirement on
mandatory support of P-channels for the mobile stations in A/Gb mode."
