[ Upstream commit 6d578258b955fc8888e1bbd9a8fefe7b10065a84 ] Coresight driver assumes sink is common across all the ETMs, and tries to build a path between ETM and the first enabled sink found using bus based search. This breaks sysFS usage on implementations that has multiple per core sinks in enabled state. To fix this, coresight_get_enabled_sink API is updated to do a connection based search starting from the given source, instead of bus based search. With sink selection using sysfs depecrated for perf interface, provision for reset is removed as well in this API.
