[PATCH stable-5.9 1/2] coresight: etm: perf: Sink selection using sysfs is deprecated

[Linu Cherian]

commit bb1860efc817c18fce4112f25f51043e44346d1b upstream.

When commit 6d578258b955 ("coresight: Make sysfs functional on
topologies with per core sink") 
was merged to stable, this patch was a pre-requisite and got
missed out leading to build breakages.

When using the perf interface, sink selection using sysfs is
deprecated.
