This will be useful for PCI based drivers to integrate fully within
the device driver model, where they will have to provide the function
they are found.

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.

The term 'context' is vague and overloaded. Its usage for 'an execution
context' is now referred as such, in both comments and some APIs' names.
When the execution context can only be a fiber or a task (i.e. not an
ISR), it is referred to as a 'thread', again in comments and everywhere
in the code.
APIs that had their names changed:
- nano_context_id_t is now nano_thread_id_t
- context_self_get() is now sys_thread_self_get()
- context_type_get() is now sys_execution_context_type_get()
- context_custom_data_set/get() are now
sys_thread_custom_data_set/get()
The 'context' prefix namespace does not have to be reserved by the
kernel anymore.
The Context Control Structure (CCS) data structure is now the Thread
Control Structure (TCS):
- struct ccs is now struct tcs
- tCCS is now tTCS

k_proc was a legacy leftover that does not make any sense, since there
is no concept of a "process" in the system. Rather, that data structure
refers to a 'task control block', i.e. the representation of a task
execution context from the microkernel's point-of-view (not to confuse
with the 'struct ccs', the representation of a thread execution context,
from the nanokernel's point-of-view).
