PSR2 vsc revision number hb2( as per table 6-11)is updated to
4 or 5 based on Y cordinate and Colorimetry Format as below
04h = 3D stereo + PSR/PSR2 + Y-coordinate.
05h = -3D stereo- + PSR/PSR2 + Y-coordinate + Pixel Encoding/Colorimetry
Format indication. A DP Source device is allowed to indicate the pixel
encoding/colorimetry format to the DP Sink device with VSC SDP only when
the DP Sink device supports it (
i.e.,VSC_SDP_EXTENSION_FOR_COLORIMETRY_SUPPORTED bit in the
DPRX_FEATURE_ENUMERATION_LIST register (DPCD Address 02210h, bit 3;
is set to 1).

v2: (Jani)
- Change DP_PSR_Y_COORDINATE to DP_PSR2_SU_Y_COORDINATE_REQUIRED.
- Add DP_PSR2_SU_GRANULARITY_REQUIRED.
- Change DPRX_FEATURE_ENUMERATION_LIST to DP_DPRX.
- Add GTC_CAP and AV_SYNC_CAP, other bits in DPRX_FEATURE_ENUMERATION_LIST.

v3: (Jani)
- Add support for bits 7:4 and 1 as per DP v1.4 for
  DPRX_FEATURE_ENUMERATION_LIST.

* [PATCH 00/10] enable psr2 for idle_screen on y-cordinate panel

This series enables psr2 on idle on screen for y cordinate panel.
Code is tested on sharp 32X18 edp 1.4 y cordinate enabled panel.
if system enters psr2, the system must go to deep sleep state.
Can be verifed by checking  psr2_status register bit 31:28.
DEEP_SLEEP[value 8]  must be entered while in idle on screen with psr2
panel.

PSR1 and PSR2 are mutually exclusive.
In the current code, when PSR2 is enabled , psr1 is also enabled,
and for psr2 the status is read from psr1 registers, leading to
blank screen.
1-3: Fixes vsc header programming for psr2 as per edp1.4 a
     table 6-11 and  blank screen issue for psr2 panel.
4-5: Enables alpm and disables aux frame sync , need for psr2.
6-7: Progarms CHICKEN_TRANS and PSR_MASK for deep sleep state, as per bspec
8:   Psr2 is enabled only for y cordinate enabled psr2 panel.
     this restriction will be removed after adding gtc support.
9-10: Adds debug support for psr2.It also enables reading of
     EDP_PSR_PERF_CNT on skl+ platforms, when dc6 is disabled through
     kernel parameter i915.enable_dc=0
