Drop support for non-programmable clocks.

From README.ati:

Clocks for supported programmable clock generators:

  The driver currently supports all programmable clock generators known
  to exist on Mach64 adapters.

Clocks for unsupported programmable clock generators:

  This case is unlikely to occur, but is documented for the sake of
  completeness.

Thus:

- check for (pATI->ProgrammableClock > ATI_CLOCK_FIXED) &&
            (pATI->ProgrammableClock < ATI_CLOCK_MAX)

- drop "probe_clocks" option

- pATIHW->ClockUnmap is no longer used

- pATIHW->ClockMap is only used with NewHW.crtc which is always ATI_CRTC_MACH64
  and has the identity map, so drop it

- (pATI->ProgrammableClock != ATI_CLOCK_INTERNAL) => (pATI->depth <= 8)
