coresight: Return the pointer of @pdata when not "fwnode"

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5YCYK



--------------------------------------------------------------------------

TRBE device can use the id_tabel to match driver. So if the CoreSight
component does not use the device tree or ACPI to report devices
(@fwnode is NULL), we need to return the pointer to the platform
data @pdata.
