drm/i915/dsi: Remove dead GLK checks

Browse Source 
GLK has its own glk_dsi_clear_device_ready() so remove
the dead GLK checks from vlv_dsi_clear_device_ready().
Sadly BXT still uses vlv_dsi_clear_device_ready() so the
code still looks like a mess due to the difference in VLV/CHV
vs. BXT port A/C shenanigans.
