pcu_l1_if_phy: add new PHY API function to disconnect PDCH
There is a function l1if_connect_pdch, but no complementary function
like we have it with l1if_open_pdch and l1if_close_pdch. The reason for
this is that the PHY implementations that rely on a femtocell DSP do not
need to disconnect the pdch explcitly. However, the planned support for
the E1 based Ercisson RBS CCU will require an explicit disconnect. So
lets add a function call for this.
