coresight: etm4x: Make etm4_remove_dev() return void
[ Upstream commit c5f231f1a7e18d28e02b282d33541d31358360e4 ]
etm4_remove_dev() returned zero unconditionally. Make it return void
instead, which makes it clear in the callers that there is no error to
handle. Simplify etm4_remove_platform_dev() accordingly.
