The OpenOCD JTAG reset causes the SAM E54 SoC to prematurely start code
execution before the SoC is ready, and this causes hard faults when the
MPU is enabled -- causing OpenOCD to hang.
This commit disables the JTAG SRST reset mechanism and falls back to
using the Cortex-M SYSRESETREQ emulation reset mechanism, which does
not have experience this issue.
