8fb2210cfb emul: remove name param from bus register APIs
Rework the <BUS>_emul_register calls to not pass the name param.  The
name param is only used for logging and we can get it from the
struct <BUS>_emul instead.

fc98549952 emul: Use DEVICE_DT_GET instead of DT_LABEL
DT nodes aren't guaranteed to define a label property. But emulated bus
controllers currently make use of this property to dispatch to the
associated emulator.

Have emulated bus controllers use DEVICE_DT_GET(node_id) to dispatch to
right target peripheral emulator. This also change makes emul_get_binding
and device_get_binding synonymous in behavior with respect to their
parameters.

This also strictly enforces a 1:1 correspondence between invocations of
DEVICE_DT_DEFINE and EMUL_DEFINE.

9d7b9dc807 emul: Simplify emulator bus initialization and API
Allow emulator creators to write an init function that can be used
across multiple busses so as to reduce the boilerplate and cognitive
load in creating an emulator.

Part of this change includes allowing access to the emul struct from a
field in a {bus}_struct api (e.g. i2c_struct), which removes the need for
sporadic usages of CONTAINER_OF to access the emul struct.

Overall, this change simplifies and reduces the amount of boilerplate
code to get a device emulator up and running, thus reducing excise work
to writing tests.

51978d9d61 driver: eSPI: npcx: workaround the errata rev1_2, No.3.10
Enabling an eSPI channel (r.g. Peripheral Channel, Virtual Wire Channel,
etc.) during an eSPI transaction might (with low probability) cause the
eSPI_SIF module to transition to a wrong state and therefore response
with FATAL_ERROR on an incoming transaction.
This CL workarounds this issue by clearing the bit 4 of NPCX eSPI
specific register#2.

1cf884786b drivers: it8xxx2: fix GPIO interrupt enables
gpio_pin_interrupt_configure asserts that one of GPIO_INT_ENABLE or
_DISABLE is specified by the caller, and also that GPIO_INT_EDGE is
requested if both states (GPIO_INT_TRIG_BOTH) should interrupt. This
change corrects the misuses in it8xxx2 drivers that cause assertion
failures.

When assertions are disabled the existing code works correctly because
the it8xxx2 GPIO driver assumes that a pin interrupt should be enabled
if _DISABLE is not requested, and the driver only supports edge
triggers but assumes the absence of GPIO_INT_MODE_LEVEL indicates
an edge trigger was requested.
