The Xe2_HPM-specific RTP table entries for Wa_16021867713 and
Wa_14019449301 were removed by commit
941f538b0af8 ("drm/xe: Consolidate
workaround entries for Wa_16021867713") and commit
aa0f0a678370
("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:

<3> [48.491238] xe 0000:03:00.0: [drm] *ERROR* Tile0: GT1: discarding save-restore reg 1d3f08 (clear:

00000020, masked: no, mcr: no): ret=-22
Re-drop the redundant Xe2_HPM-specific entries to eliminate the dmesg
errors.
