Introduces the SYS_DEFINE_DEVICE() macro, which supports 5 distinct
levels of device initialization and 100 priorities within each level.
Note: The existing init macros (e.g. nano_early_init()) have been
adapted to utilize the enhanced initialization model, but will
eventually be retired.

Gets rid of the trailing initialization level character from the
name of the device variable generated by the macro, since it serves
no useful purpose. (The linker scripts place the various initialization
sections in ascending order based on the name of the section, so there
is no need to embed the initialization level in the variable name itself.)

Reworks the internal design of a command packet set so that
the command packet array is split out into a separate variable
lying in uninitialized memory. This shrinks the command packet's
data section footprint to almost nothing.
Note: A side effect of this change is that it is no longer possible
to define a command packet set as a "static" variable since the
CMD_PKT_SET_INSTANCE() macro now generates two variables.

This functions - reusing _arc_v2_aux_reg_* ones - will ease porting
drivers to ARC architecture hiding arch specific calls under generic
functions. On ARC, auxiliary registers is conceptually comparable to
x86 ports, thus the possibility to bring sys_in/sys_out to access those.

GPIO driver is initialized at pre-kernel-late level, if SPI does it too,
it will happen before GPIO (depends on the ordered list of
initialization). In order to ensure it gets GPIO initialized always
before SPI, let's set SPI to initalize at the next level: nano-early.

Updates the 'gen_idt' tool to generate a bitmap of (statically) allocated
interrupt vectors that is linked into the final image in a manner similar to
the static IDT. The kernel then uses this bitmap when dynamically connecting
an interrupt vector, thereby preventing the dynamic irq connections
from clobbering the static irq connections.

Adds two new fields to the ISR_LIST structure (irq and priority) to allow
the decoupling of the vector ID and priority from the IRQ number at some
future time.
As a result of the addition of these two new fields, the gen_idt tool is
modified to both process these new fields as well as validate them.

Fixes a bug in the x86 IRQ_CONNECT_STATIC() macro that resulted in setting
the DPL for the interrupt to the IRQ priority level.
Note 1: Using a proper value for the DPL (instead of the priority) prevents
the corruption of the other IDT fields.
Note 2: The priority of the IRQ is completely ignored.

Instead of using logic choosing between invoking find_lsb_set() and
find_msb_set(), mask out the unwanted bits and always invoke find_lsb_set().
This also has the side benefit of simplifying the error checking when DEBUG is

Originally, the config_whitelist was done on the platform level
ignoring any config options in the testcase. This change generates
the defconfig for all relevant testcases that have config_whitelist
and applies filters based on the testcase defconfig.
If we have many testcases using config_whitelist it might be a bit
slower, but it is more accurate.

Provides a way for a fiber or task to busy wait for a specified
period of time. This is useful in situations where a delay needs
to be performed without switching execution to another context,
such as:
1) It would take longer to switch to another context and then switch
back again than to simply busy wait.
2) A delay is required by the kernel's main task (i.e. the nanokernel's
background task or the microkernel's idle task). This task is not
allowed to voluntarily relinquish the CPU because this would leave
the kernel with nothing to execute in its place.
