drm/xe/wa: Drop redundant entries for Wa_16021867713 & Wa_14019449301

Browse Source 
The Xe2_HPM-specific RTP table entries for Wa_16021867713 and
Wa_14019449301 were removed by commit 941f538b0a ("drm/xe: Consolidate
workaround entries for Wa_16021867713") and commit aa0f0a6783
("drm/xe: Consolidate workaround entries for Wa_14019449301") in favor
of alternate entries earlier in the table that cover a wider range of IP
versions.  However these Xe2_HPM-specific entries were accidentally
resurrected during a backmerge, which causes the Xe driver to complain
on probe about two entries trying to program the same registers+bits:

  <3> [48.491155] xe 0000:03:00.0: [drm] *ERROR* Tile0: GT1: discarding save-restore reg 1c3f1c (clear: 00000008, set: 00000008, masked: no, mcr: no): ret=-22
  <3> [48.491211] xe 0000:03:00.0: [drm] *ERROR* Tile0: GT1: discarding save-restore reg 1d3f1c (clear: 00000008, set: 00000008, masked: no, mcr: no): ret=-22
  <3> [48.491225] xe 0000:03:00.0: [drm] *ERROR* Tile0: GT1: discarding save-restore reg 1c3f08 (clear: 00000020, set: 00000020, masked: no, mcr: no): ret=-22
  <3> [48.491238] xe 0000:03:00.0: [drm] *ERROR* Tile0: GT1: discarding save-restore reg 1d3f08 (clear: 00000020, set: 00000020, masked: no, mcr: no): ret=-22

Re-drop the redundant Xe2_HPM-specific entries to eliminate the dmesg
errors.
