perf vendor events arm64: Fill up Desc field for Hisi hip08 hha pmu

In the same PMU, when some JSON events have the "BriefDescription" field
populated while others do not, the cmp_sevent() function will split these
two types of events into separate groups. As a result, when using perf
list to display events, the two types of events cannot be grouped together
in the output.

before patch:
 $ perf list pmu
 ...
 uncore hha:
   hisi_sccl1_hha2/sdir-hit/
   hisi_sccl1_hha2/sdir-lookup/
 ...
 uncore hha:
   edir-hit
      [Count of The number of HHA E-Dir hit operations. Unit: hisi_sccl1_hha2]
 ...

after patch:
 $ perf list pmu
 ...
 uncore hha:
   edir-hit
      [Count of The number of HHA E-Dir hit operations. Unit: hisi_sccl1_hha2]
   sdir-hit
      [Count of The number of HHA S-Dir hit operations. Unit: hisi_sccl1_hha2]
   sdir-lookup
      [Count of the number of HHA S-Dir lookup operations. Unit: hisi_sccl1_hha2]
