Use of these is the mark of a deranged imagination.

These are guaranteed to work for bitfields that are
larger then 32 bits wide.

sys_io.h documents the functions but does not include the
actual implementation. Make it include nanokernel.h which
would then pick the right arch.h where the sys_io are implemented.

This will be helpful also in drivers mostly, where non-atomic bit
setting could be unnecessary.

sys_io.h header file declares the generic API for such operations. It
properly separates port and memory mapped registers, with declaring
respective types: io_port_t and mm_reg_t.
Memory mapped registers are the most common type of registers drivers
will play with. Thus providing generic sys_readX/sys_writeX functions in
sys_io.h. Those are defined as inline as they are really simple.
Ports are mostly (always?) found in x86 architecture.
Currently no ARM or ARC header file propose any implementation of
those. If really necessary (a cross-architecture driver using
sys_in/sys_out functions), those architecture will provide the proper
implementation or at least a macro gluing those towards
sys_read/sys_write.
