drm/i915: update the QGV point frequency calculations
From MTL onwwards, pcode locks the QGV point based on peak BW of
the intended QGV point passed by the driver. So the peak BW
calculation must match the value expected by the pcode. Update
the calculations as per the Bspec.
v2: use DIV_ROUND_* macro for the calculations (Ville)
v3: Use only DIV_ROUN_CLOSEST and remove divisor / 2 again
Bspec: 64636
