[PATCH] drm/i915/display: make update_ref_clks vfunc mandatory

[Lucas De Marchi]

Commit ccc495fd7ac3 ("drm/i915: Unify the DPLL
ref clock frequency tracking") added a new vfunc in pll mgr, but made it
optional. However all platforms need a ref clk in their calculations.
Make this vfunc mandatory so it's not a silent fail but a very obvious
one.
