acf1939a4c drivers: entropy: Convert drivers to new DT device macros 
Convert entropy drivers to use new DT variants of the DEVICE APIs.
    DEVICE_AND_API_INIT -> DEVICE_DT_DEFINE
    DEVICE_GET -> DEVICE_DT_GET

etc..

e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

af6140cc0d device: Apply config_info rename everywhere 
Via coccinelle:

@r_device_config@
struct device *D;
@@

D->
-	config_info
+	config

And 2 grep/sed rules for macros:

git grep -rlz 'dev)->config_info' |
	xargs -0 sed -i 's/dev)->config_info/dev)->config/g'

git grep -rlz 'dev->config_info' |
	xargs -0 sed -i 's/dev->config_info/dev->config/g'

Fixes #27397

97326c0445 device: Fix structure attributes access 
Since struct devconfig was merged earlier into struct device, let's fix
accessing config_info, name, ... attributes everywhere via:

grep -rlZ 'dev->config->' | xargs -0 sed -i 's/dev->config->/dev->/g'

9be31b5aa4 drivers: entropy: Convert drivers to use DT for label 
Move towards use DTS for driver instance name instead of Kconfig sybmol.
This is towards phasing out CONFIG_ENTROPY_NAME.

969f8f1c68 cleanup: include/: move entropy.h to drivers/entropy.h 
move entropy.h to drivers/entropy.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

8b883a61a3 subsys/random: sys_rand32_get() implementation that uses entropy API 
Instead of every hardware number generator driver providing an
implementation of this function, use the random device API to
centralize the implementation of this function.

This is a very simplistic function that can be seen as a stepping stone
to refactor the random number generation in Zephyr.

da9b0ddf5b drivers: Rename random to entropy 
This should clear up some of the confusion with random number
generators and drivers that obtain entropy from the hardware.  Also,
many hardware number generators have limited bandwidth, so it's natural
for their output to be only used for seeding a random number generator.
