drm/i915: Compute DSI PLL parameters during .compute_config()
Compute the DSI PLL parameters during .compute_config() rather than
.pre_pll_enable() so that we can fail gracefully if we can't find
suitable parameters.
In order to do that we need to store the DSI PLL parameters in
pipe_config.
v2: Handle BXT too
