drm/xe: Merge 16021540221 and 18034896535 WAs
In order to detect duplicate implementations for the same workaround,
early in the implementation of RTP it was decided to error out even if
the values set are exactly the same. With the introduction of 18034896535
in commit 74671d23ca18 ("drm/xe/xe2: Add workaround 18034896535"), LNL
stepping with graphics stepping A1 now gives the following error on
module load:
xe 0000:00:02.0: [drm] *ERROR* GT0: [GT OTHER] \
discarding save-restore reg e48c (clear: 00000200, set: 00000200,\
masked: yes, mcr: yes): ret=-22
RTP may be improved in the future, but for now simply join the entries
like done with e.g. "1607297627, 1607030317, 1607186500".
