Commit 1c8859848dbb ("coresight replicator: Cleanup programmable
replicator naming") changed the Kconfig symbol name from
QCOM_REPLICATOR, which, whilst not in the single arm64 defconfig,
was being set in my juno build script, which left the new symbol unset,
causing the following unexpected grief:
# ./perf record -vvv -C 0 -e cs_etm/@20070000.etr/ --per-thread true
..<snip>..
sys_perf_event_open: pid -1 cpu 0 group_fd -1 flags 0x8 = 5
mmap size 528384B
AUX area mmap length 4194304
perf event ring buffer mmapped per cpu
failed to mmap AUX area
failed to mmap with 12 (Cannot allocate memory)
Make it default y to help not surprise unsuspecting users.
