Following the idiom used for system calls, add script support to read
the initial application binary to identify which devices are defined,
and to use their offset in the device array as their unique handle
rather than the externally-defined ordinal from devicetree. The
device dependency arrays are updated to use these handles.

Generate arrays of dependency information for each device. If a
device definition is being constructed from devicetree these come from
the devicetree dependency information. Additional dependencies may be
passed through using the DT_ macros.
Define flag values for device handles so we can partition the
dependency array into distinct sets, which include things it requires,
things it supports (may not be needed), and child nodes (not
implemented, may not be needed).

Move the busy status from a global atomic bit sequence to atomic flags
in the device PM state. While this temporarily adds 4 bytes to each

it's likely the extra memory can be recovered.

Separate the state indicator of whether the initialization function
has been invoked from the success or failure of the initialization.
This allows precise confirmation that the device is ready (i.e. it has
been initialized, and that initialization succeeded).

This avoids the need for distinct object that uses flash to store its
initializer. Instead the state is initialized when the kernel is
starting up, before anything can reference it. In future refactoring
the PM state could be accessed directly without storing an extra
pointer in the static device state.

Initialize all device objects in a batch before invoking any code that
might try to reference data in them. This eliminates a race condition
enabled by the ability to resolve a device structure at build time,
and reference it from one device's initialization routine before the
device itself has been initialized.
While the device is pulled from the sys_init records rather than
static devices, all in-tree init_entry records that are associated
with devices are produced via Z_DEVICE_DEFINE(), so there should be no
static devices that would be missed by instead iterating over the
device records.

This fixes the logic in erase_sector() for clearing the previous
sector number. The logic was reversed, clearing bits it should not
clear and keeping previous bits of the sector number. In practice this
does not seem to have had any effect on the current functionality, but
it will start to matter later if e.g. flash interrupts are enabled.

This driver emulates a EEPROM device in flash.
Reworked implementation with modified flash layout.
The emulation represents the EEPROM in flash as a region that is a
direct map of the eeprom data followed by a region where changes to
the eeprom data is stored. Changes are written as address-data
combinations. The size of such a combination is determined by the
flash write block size and the size of the eeprom (required address
space), with a minimum of 4 byte.
The eeprom page needs to be a multiple of the flash page. Multiple
eeprom pages is also so supported and increases the number of writes
that can be performed.
The eeprom size, pagesize and the flash partition used for the eeprom
are defined in the dts. The flash partition should allow at least two
eeprom pages. For fast read access a rambuffer can be enabled for the
eeprom (by setting the option rambuf in the dts).

As we add support for devices that are powered down, or are present
but have not yet been started, we need more precise information about
why a device isn't ready, so callers can take appropriate steps to
make it ready.
Add a new function that determines readiness and indicates the reason
for not being ready in a defined unique error code per condition.
Expose this in both a syscall form to be invoked from applications,
and a unchecked form that can be used from supervisor contexts
including syscall implementation functions.
Anticipated future conditions include:
* device is powered down and needs to be brought back up;
* device was installed disabled and has not been started.
