Subject: [PATCH v2 0/3] SBI PMU event related fixes

Here are two minor improvement/fixes in the PMU event path. The first patch
was part of the series[1]. The 2nd patch was suggested during the series
review. 

While the series can only be merged once SBI v3.0 is frozen, these two
patches can be independent of SBI v3.0 and can be merged sooner. Hence, these
two patches are sent as a separate series.
