nrf: etm-trace for nrf52840dk and nrf5340dk
nrf52840dk: 16 MHz TRACECLK (hardware cap) width 4, P25 soldered, SW7=Alt;
no family code needed (J-Link arms TRACECONFIG). nrf5340dk: TRACE_ETM
builds force the TAD port to 16 MHz (SystemInit's 64 MHz is marginal),
+3 ns sample timing; the interface MCU's UART1 flow control drives the
trace pins - SB27/SB28 must be cut (P0.10/P0.11 = TRACEDATA1/0).
