drm/i915: Add pineview_update_wm callback to update watermark for pineview

Now we don't define the update_wm callback function explicitly for
pineview platform. But as it also belongs to mobile platform, we will
use the function of i9xx_update_wm function to update its watermark again
after we configure the watermark. This is incorrect.

So we will add a update_wm callback function for pineview to update watermark.

BTW: We will disable the self-refresh and never enable it any more if we
can't find the appropriate the latency on pineview plaftorm. In such case
the update_wm callback will be NULL.

The bitmask macro is also defined to access the corresponding fifo
watermark register.
