From: Leo Yan leo.yan@linaro.org
mainline inclusion from mainline-v5.11-rc1 commit 889d1a675fcf category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4NGPV CVE: NA
-------------------------------------------------
Move the enums of event types to arm-spe-pkt-decoder.h, thus function arm_spe_pkt_desc_event() can use them for bitmasks.
