cpu/cc2538: add Watchdog implementation
...
The Watchdog on the CC2538 only supports 4 intervals (2ms, 16ms, 250ms & 1s).
Since the watchdog timer API specifies a `max_time`, the interval equal or
below that time is selected.
E.g. for `max_time=125ms` the 16ms interval would be selected.
This is outside the tolerance of the `tests/periph_wdt` test.

fe310: Use read-modify-store instruction on GPIO
...
The rv32imac supports the A (atomic) extensions containing
read-modify-store operations. This commit modifies the GPIO code to use
these for all bitwise operations. The atomic operations are emitted with
relaxed ordering as they do not require multiprocessor synchronization.
This decreases the duration of the gpio operations from 59 ns to 50 ns
per call. depending a bit on the type of operation.

fe310: Split sched_run call from handle_trap
...
This is a small optimization to the RISC-V trap handler. By splitting
the call to sched_run from the trap_handle call, loading the previous
thread ptr can be delayed until after it is determined that a schedule
run is required. This shaves of a few cycles during regular interrupts
that do not trigger the scheduler.

This commit reworks the trap entry to only save the callee-saved
registers when a context switch is required. the caller-saved registers
are always stored and restored to adhere to the RISC-V ABI. This saves
considerable cycles on interrupts.

socket_zep: fix reboot
...
The `_zep_params_setup()` function will modify the `argv` string passed to it.
This is a problem because that string is re-used on reboot.
The modified string is then later processed in `socket_zep_setup()`, so we have to keep
the memory around.
The `strdup()` fulfills all this and the memory is freed by `execve()` on reboot.
A proper solution would be to parse the strings in `_zep_params_setup()`.

While the hard fault handler prints the offending program counter, it
does not print information about the context triggering the hard fault.
This commit adds a line printing the thread ID and name that triggered
the hard fault. If the hard fault is triggered during an ISR, it only
prints that the hard fault happened during ISR context, not which ISR
triggered it.
