PCUIF_Components: add compatibility for PCU_IF_SAPI_AGCH_2

When we receive a PCUIF_DATA_REQ, f_BTS_CT_handler will mangle the
incoming message for us. The resulting BTS_CCCH_Block that is sent up to
the component not only contains the PCUIF message, but will also have
the already parsed MAC block attached. This currently only works for
PCU_IF_SAPI_PCH and PCU_IF_SAPI_PCH_2 but not for PCU_IF_SAPI_AGCH_2.

Let's add compatibility for PCU_IF_SAPI_AGCH_2.
