crtc_clock is now supposed to be the actual pixel clock corresponding to
the other crtc_ timing values. Populate crtc_clock appropriately in
radeon_atom_get_tv_timings().

This was the only obvious place where we frob with the crtc_ timigns
directly instead of calling drm_mode_set_crtcinfo() which would also
update crtc_clock.

drivers: gpu: Move prototype declarations to header file radeon_mode.h from radeon_atombios.c and radeon_combios.c

Move prototype declarations of functions radeon_get_encoder_enum() and
radeon_link_encoder_connector() to header file drm/radeon/radeon_mode.h
because they are used by more than one file.

This eliminates the following warnings in drm/radeon/radeon_encoders.c:

The table has the following format:

typedef struct _ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT         //usSrcDstTableOffset pointing to this structure
{
  UCHAR               ucNumberOfSrc;
  USHORT              usSrcObjectID[1];
  UCHAR               ucNumberOfDst;
  USHORT              usDstObjectID[1];
}ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT;

usSrcObjectID[] and usDstObjectID[] are variably sized, so we
can't access them directly.  Use pointers and update the offset
appropriately when accessing the Dst members.
