[linux-yocto] [PATCH v2 00/12] ktype refactoring: move DEBUG_KERNEL, EXPERT and EMBEDDED

Targetted for yocto-4.4 and master.

Changes since last revision:

*Renamed extended to developer*
More descriptive name than extended.

*Add DEBUG_PREEMPT to debug-kernel feature*
This is an important debug feature that we should explicitly enable.
Enabling CONFIG_DEBUG_MUTEXES was also proposed, but I decided to leave
that out for now, as it is new functionality and I want to keep it as
close as possible to previous functionality for this refactoring

*Removed HID disabling patch*
We had somebody run into a keyboard not working because the HIDs were
not enabled. These will probably be enabled in base eventually.

*Removed PROCESSOR_SELECT from intel-core2-32.cfg*
Forgot this my first pass. Without EXPERT we don't get this option and
the kernel_configcheck task gives us a warning.

*Explicitly enable DEBUG_KERNEL in developer.cfg*
I want it to be absolutely clear we get DEBUG_KERNEL, even when
inheriting developer nocfg.

*Updated commit messages
Minor things like bsp -> BSP, as well as updates based on the above changes.

This patch series refactors the ktypes so that base and standard ktypes
do not enable EMBEDDED, EXPERT, or DEBUG_KERNEL. The reason this
decision was made is because production platforms likely do not want
DEBUG_KERNEL enabled, and EMBEDDED selects EXPERT which selects

A new ktype called "developer" was also created. This ktype
enables the options now missing from standard and base, making it easy
to maintain the functionality of a BSP through simply swapping the ktype
from standard to developer. The preempt-rt ktype is now based off of
developer in order to maintain its functionality.

The new standard ktype does not include EMBEDDED, EXPERT, or
DEBUG_KERNEL. Without DEBUG_KERNEL it loses a number of debug features
that are selected by default. Without EXPERT it gains RFKILL_INPUT and
DEBUG_MEMORY_INIT, while losing VMSPLIT_3G. These are only available to
configure with CONFIG_EXPERT=y and default to EXPERT or !EXPERT. Not
selecting EMBEDDED has no apparent impacts.

Some coordination is required for this change, as existing BSPs WILL be
affected, and will either need to accept the changes in the standard
ktype or move to the developer ktype.
