drivers/perf: hisi: Fix data source control
mainline inclusion from mainline-v5.13-rc3 commit 814be609 category: bugfix bugzilla: 175148 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=814be609baae62aaa6c02fa6f3ad66cff32a6d15 ------------------------------------------------------------------------ 'Data source' is a new function for HHA PMU and config / clear interface was wrong by mistake. 'HHA_DATSRC_CTRL' register is mainly used for data source configuration, if we enable bit0 as driver, it will go on count the event and we didn't check it carefully. So fix the issue and do as the initial purpose.
