Hi,

There is a no "one size fits all" solution for configuring a PREEMPT_RT
kernel.

Intorduce a PREEMPT_RT kernel configuration guide to better help system
developers and integrators.

Changelog v4
------------

Handle Sashiko review: Remove a no-longer-referenced link.  Remove
CONFIG_WQ_SYS reference, which I thought it exists due to a quick
misunderstanding of core-api/workqueue.

Changelog v3
------------

CONFIG_EFI_DISABLE_RUNTIME: Mention that system integrators can now assign
the efi_runtime workqueue CPU affinity, then safely pin RT tasks on a
different CPU range.

Changelog v2
------------

Handle Rostedt remarks:

- Better reword certain paragraphs and statements
- Warn about enabling CONFIG_IRQSOFF_TRACER and CONFIG_PREEMPT_TRACER

Handle Wilcox remarks:

- Remove ToC comment + minor rewording

Changelog v1
------------
