drm/xe: Drop redundant rtp entries for Wa_14019988906 & Wa_14019877138

There appears to have been a silent merge conflict between some commits
updating the workaround tables on Xe's -fixes and -next branches:

 - Commit bc6387a2e0c1 ("drm/xe/xe2_hpg: Fix handling of Wa_14019988906
   & Wa_14019877138") from the fixes branch moved the Xe2_HPG instance
   of two workarounds touching the PSS_CHICKEN register from the
   engine_was[] table to the lrc_was[] table; the equivalent
   implementation for all other platforms/IPs were already properly
   located on lrc_was[].  This commit on the fixes branch is a
   cherry-pick of commit e04c609eedf4 ("drm/xe/xe2_hpg: Fix handling of
   Wa_14019988906 & Wa_14019877138") that already existed on the next
   branch.

 - Commit 55b19abb6c44 ("drm/xe: Consolidate workaround entries for
   Wa_14019877138") and commit c2142a1a8415 ("drm/xe: Consolidate
   workaround entries for Wa_14019988906") consolidated the individual
   entries per IP generation for each workaround into single, larger
   range-based entries.

During merge conflict resolution the Xe2_HPG-specific entries (i.e.,
those with rule "GRAPHICS_VERSION_RANGE(2001, 2002)") were accidentally
resurrected, even though the table already contains the consolidated
entries that match a superset of thse ranges.  These redundant entries
don't cause any build failures but do trigger a dmesg error during probe
on BMG-G21 devices:

  xe 0000:03:00.0: [drm] *ERROR* Tile0: GT0: discarding save-restore reg 7044 (clear: 00000400, set: 00000400, masked: yes, mcr: yes): ret=-22
  xe 0000:03:00.0: [drm] *ERROR* Tile0: GT0: discarding save-restore reg 7044 (clear: 00000020, set: 00000020, masked: yes, mcr: yes): ret=-22

Re-drop the Xe2_HPG-specific table entries to eliminate the error.
