mainline inclusion from mainline-v5.7-rc1 commit bc88a2fe216a51e8ab46d61f89d0c1b5a400470e category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I47H3V CVE: NA
--------------------------------
commit bc88a2fe216a51e8ab46d61f89d0c1b5a400470e upstream.
Backport summary: Backport to kernel 4.19.57 for ICX uncore support.
The offset between uncore boxes of free-running counters varies, e.g. IIO free-running counters on Ice Lake server.
Add box_offsets, an array of offsets between adjacent uncore boxes.
