gcc -Wextra points out a duplicate initialization of one array
member:

arch/x86/events/intel/uncore_snb.c:478:37: warning: initialized field overwritten [-Woverride-init]
  478 |  [SNB_PCI_UNCORE_IMC_DATA_READS]  = { SNB_UNCORE_PCI_IMC_DATA_WRITES_BASE,

The only sensible explanation is that a duplicate 'READS' was used
instead of the correct 'WRITES', so change it back.

Fixes: 24633d901ea4 ("perf/x86/intel/uncore: Add BW counters for GT, IA and IO breakdown")
