perf arm-spe: Convert event kernel time to counter value

mainline inclusion
from mainline-v5.14-rc1
commit 63051901
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4NGPV
CVE: NA

-------------------------------------------------

When handle a perf event, Arm SPE decoder needs to decide if this perf
event is earlier or later than the samples from Arm SPE trace data; to
do comparision, it needs to use the same unit for the time.

This patch converts the event kernel time to arch timer's counter value,
thus it can be used to compare with counter value contained in Arm SPE
Timestamp packet.
