The x86 architecture is no longer the only one that supports hardware
floating point operations.

Move to use :option:`CONFIG_XYZ` vs :option:`XYZ` to generate propert
links and avoid warnings about unexistant targets.

A couple paragraphs contain ambiguous verbs that are unclear.
(For example: Line 23. Does the kernel perform a busy-wait,
or does it merely permit a task or fiber to perform a busy-wait?)
Based on original, I guess the latter and attempted to correct this
in the docs.
Also fixed spelling error.

Change the terminology in the documentation and use board instead
of platform where applicable.

Change terminology and use SoC instead of platform. An SoC provides
features and default configurations available with an SoC. A board
implements the SoC and adds more features and IP block specific to the
board to extend the SoC functionality such as sensors and debugging
features.

Removes the following deprecated routines:
nano_cycle_get_32()
task_cycle_get_32()
fiber_cycle_get_32()
isr_cycle_get_32()
Those routines have all been replaced by sys_cycle_get_32().

Replaces calls to nano_cycle_get_32() and task_cycle_get_32()
with sys_cycle_get_32() as that is the preferred API to use.

Renames _sys_clock_cycle_get() (provided by the timer driver)
to sys_cycle_get_32(). It is the preferred method to read the
hardware clock.

Removes the following context based APIs:
isr_tick_get_()
isr_tick_get_32()
fiber_tick_get()
fiber_tick_get_32()
The routines sys_tick_get() and sys_tick_get_32() are to be used instead.

The tables in the Kernel Primer are changed to lists. Making it easier
to update them. Other minor changes were done to ensure consitency.
The :c: and :cpp: markup has been fixed. When the documentation for a
call exists, then it is linked.

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
