drm/i915/adl_s: Add ADL-S platform info and PCI ids

- Add the initial platform information for Alderlake-S.
- Specify ppgtt_size value
- Add dma_mask_size
- Add ADLS REVIDs
- HW tracking(Selective Update Tracking Enable) has been
  removed from ADLS. Disable PSR2 till we enable software/
  manual tracking.

v2:
- Add support for different ADLS SOC steppings to select
  correct GT/DISP stepping based on Bspec 53655 based on
  feedback from Matt Roper.(aswarup)

v3:
- Make display/gt steppings info generic for reuse with TGL and ADLS.
- Modify the macros to reuse tgl_revids_get()
- Add HTI support to adls device info.(mdroper)

v4:
- Rebase on TGL patch for applying WAs based on stepping info from
  Matt Roper's feedback.(aswarup)

v5:
- Replace macros with PCI IDs in revid to stepping table.

v6: remove stray adls_revids (Lucas)
