drm/i915/debugfs: New debugfs for display clock frequencies
Instead of mixing display & non-display stuff together, move
display specific clock info to new debugfs. This patch will
create a new debugfs "i915_cdclk_info" to expose Current & Max
cdclk and Max pixel clock frequency info.
Example:
$ cat /sys/kernel/debug/dri/0/i915_cdclk_info
Current CD clock frequency: 163200 kHz
Max CD clock frequency: 652800 kHz
Max pixel clock frequency: 1305600 kHz
V2: - s/i915_display_clock_info/i915_cdclk_info/ (Jani)
- Move the logic to intel_cdclk.c (Jani)
- Don't remove info from i915_frequency_info (Jani)
V3: - Drop locking (Jani)
