drm/i915/lt_phy: Replace crtc compute clock
The existing DPLL compute clock callback for the XE3PLPD platform
(`xe3plpd_crtc_compute_clock`) was specific to that platform. Replace it
with the more generic Haswell (`hsw_crtc_compute_clock`) implementation
so that the compute clock path does not rely on the XE3PLPD hook.
