rename sysmo_direct_dsp to direct_phy

The name sysmo_direct_dsp is not entirely correct. It should be just
"sysmo" if we follow the rules that the "PCU_IF_FLAG_" prefix is
supposed to be chopped off here.

In pcuif_proto.h, we have renamed PCU_IF_FLAG_SYSMO to
PCU_IF_FLAG_DIRECT_PHY. (see Depends), so let's rename the flag here to
"direct_phy".
