The i845_update_wm code was always calling the i845 variant,
and the i9xx_update_wm had only a choice between i830 and i9xx
paths, hardly worth the vfunc overhead.

This moves one wrapper from the pm->display side, and creates
wrappers for all the others, this should simplify things later.
One thing to note is that the code checks the existance of some
of these ptrs, so the wrappers are a bit complicated by that.
Suggested by Jani.
v2: fixup warnings in wrong place error.

- * intel_update_watermarks - update FIFO watermark values based on current modes
- * @dev_priv: i915 device
- *
- * Calculate watermark values for the various WM regs based on current mode
- * and plane configuration.
- *
- * There are several cases to deal with here:
- * - normal (i.e. non-self-refresh)
- * - self-refresh (SR) mode
- * - lines are large relative to FIFO size (buffer can hold up to 2)
- * - lines are small relative to FIFO size (buffer can hold more than 2
- * lines), so need to account for TLB latency
- *
- * The normal calculation is:
- * watermark = dotclock * bytes per pixel * latency
- * where latency is platform & configuration dependent (we assume pessimal
- * values here).
- *
- * The SR calculation is:
- * watermark = (trunc(latency/line time)+1) * surface width *
- * bytes per pixel
- * where
- * line time = htotal / dotclock
- * surface width = hdisplay for normal plane and 64 for cursor
- * and latency is assumed to be high, as above.
- *
- * The final value programmed to the register should always be rounded up,
- * and include an extra 2 entries to account for clock crossings.
- *
- * We don't use the sprite, so we can ignore that. And on Crestline we have
- * to set the non-SR watermarks to 8.

however the fdi use of the vtable is limited to only a
few generations.

this single function might be possible to merge later, but
