coresight: etm4x: Drop pid argument from etm4_probe()
mainline inclusion from mainline-v6.5-rc1 commit 5a1c7097 category: Cleanup bugzilla: https://gitee.com/openeuler/kernel/issues/I89TNS CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=5a1c7097472fcde5745654e3a59f55140903d9cc -------------------------------- Coresight device pid can be retrieved from its iomem base address, which is stored in 'struct etm4x_drvdata'. This drops pid argument from etm4_probe() and 'struct etm4_init_arg'. Instead etm4_check_arch_features() derives the coresight device pid with a new helper coresight_get_pid(), right before it is consumed in etm4_hisi_match_pid().
