samd5x_e5x: ETM trace support for same54_xplained
The populated 20-pin Cortex Debug+ETM header carries 4-bit trace
(TRACECLK=PC27, D0-3=PC28/PC26/PC25/PC24, mux H). TRACE_ETM builds mux
the pins and enable GCLK channel 47 (GCLK_CM4_TRACE) from GCLK0 - without
that gate the port stays silent with pins and TPIU armed. Chip-max
120 MHz core / 60 MHz TRACECLK validated (3x 280M-fetch captures).
