riscv_fork.c: Fix race condition when handling parent integer registers

We need to record the parent's integer register context upon exception
entry to a separate non-volatile area. Why?

Because xcp.regs can move due to a context switch within the fork() system
call, be it either via interrupt or a synchronization point.

Fix this by adding a "sregs" area where the saved user context is placed.
The critical section within fork() is also unnecessary.

+-  ``struct ioexpander_ops_s``. Each ioexpand device driver must implement
+   an instance of ``struct ioexpander_ops_s``. That structure defines a
+   call table with the methods, and we also provide macros to help access methods.
+
+-  we also provide method ``gpio_lower_half`` to make ioexpander compatible with normal gpio.
+
+-  **Binding ioexpander Drivers**. ioexpander drivers are not normally directly
+   accessed by user code, we should always get lower level drivers, for example I2C,
+   and map extended gpio feature same asa normal gpio. See for example,
+   ``int nrf52_sx1509_initialize(void)``
+   in ``boards/arm/nrf52/thingy52/src/nrf52_sx1509.c``. In general, the binding
+   sequence is:
+
+   #. Get an instance of ``struct i2c_master_s`` from the
+      hardware-specific I2C device driver, and
+   #. Provide that instance and configurations to the ioexpander initialization method
+      to get the ``struct ioexpander_dev_s`` ioe device instance.
+   #. Then use ioe device instance to do ioexpander operations, or use ``gpio_lower_half``
+      to make ioexpand compatible with normal gpio.
+
+
+-  **Examples**: ``drivers/ioexpander/pca9555.c``,
+   ``drivers/input/aw86225.c``,
+   ``drivers/analog/lmp92001.c``,
+   ``drivers/ioexpander/ioe_rpmsg.c``,
+   ``boards/sim/sim/sim/src/sim_ioexpander.c``,
+   ``boards/arm/nrf52/thingy52/src/nrf52_sx1509.c`` etc.
