How about

#define FDIA_PHASE_SYNC_OVERRIDE_SHIFT  19
#define FDIA_PHASE_SYNC_ENABLE_SHIFT    18
#define FDI_PHASE_SYNC_OVERRIDE(pipe) (1 << (FDIA_PHASE_SYNC_OVERRIDE_SHIFT - (pipe) * 2))
#define FDI_PHASE_SYNC_ENABLE(pipe)   (1 << (FDIA_PHASE_SYNC_ENABLE_SHIFT - (pipe) * 2))

defines instead?

Then use FDI_PHASE_SYNC_OVERRIDE(pipe) | FDI_PHASE_SYNC_ENABLE(pipe)

in the code.
