Lourens Naude 447ebd7fd5 arch/arm/src/imxrt: Start the DWT cycle counter for perf events.
CONFIG_ARCH_PERF_EVENTS is on by default for ARMv7-M, but imxrt never
called up_perf_init(), so perf_gettime() read zero and anything timed
with it, rpmsg_ping for one, reported 0 ns.  Initialise the counter with
BOARD_CPU_FREQUENCY after the MPU is set up, as samv7 and stm32h7 do.
