drm/i915: Add debugfs entry for DRRS
Adding a debugfs entry to determine if DRRS is supported or not
V2: [By Ram]: Following details about the active crtc will be filled
in seq-file of the debugfs
1. Encoder output type
2. DRRS Support on this CRTC
3. DRRS current state
4. Current Vrefresh
Format is as follows:
CRTC 1: Output: eDP, DRRS Supported: Yes (Seamless), DRRS_State: DRRS_HIGH_RR, Vrefresh: 60
CRTC 2: Output: HDMI, DRRS Supported : No, VBT DRRS_type: Seamless
CRTC 1: Output: eDP, DRRS Supported: Yes (Seamless), DRRS_State: DRRS_LOW_RR, Vrefresh: 40
CRTC 2: Output: HDMI, DRRS Supported : No, VBT DRRS_type: Seamless
V3: [By Ram]: Readability is improved.
Another error case is covered [Daniel]
V4: [By Ram]: Current status of the Idleness DRRS along with
the Front buffer bits are added to the debugfs. [Rodrigo]
V5: [By Ram]: Rephrased to make it easy to understand.
And format is modified. [Rodrigo]
V6: [By Ram]: Modeset mutex are acquired for each crtc along with
renaming the Idleness detection states [Daniel]

[danvet: dump full busy_frontbuffer_bits and remove the dubios
computed logical state of DRRS - debugfs is about what is fact,
developers should reach their own conclusion when debugging issues.]
