Mike Leach 9f37d37980 coresight: etm4x: Fix missing trctraceidr file in sysfs
The trace ID patchset adjusted the handling of the TRCTRACEIDR register
sysfs to allocate on read.

Although this was initally correct, the final version of the patch series
introduced an error which resulted in the mgmt/trctraceidr file in sysfs
not being visible.

This patch fixes that issue.
