[Intel-gfx] [PATCH 1/1] drm/i915/debugfs: New debugfs for display clock frequencies

[Bhanuprakash Modem]

Instead of mixing display & non-display stuff together, move
display specific clock info to new debugfs. This patch will
move Current & Max cdclk and Max pixel clock frequency info
to the new debugfs file "i915_display_clock_info".
