coresight: tpdm: add static tpdm support

Browse source

The static TPDM function as a dummy source, however, it is essential
to enable the port connected to the TPDA and configure the element size.
Without this, the TPDA cannot correctly receive trace data from the
static TPDM. Since the static TPDM does not require MMIO mapping to
access its registers, a clock controller is not mandatory for its
operation.
