86bfc489f4 scripts: Replace hard-coded subsystem list with __subsystem annotations.
This change removes the hardcoded subsystem list in gen_kobject_list.py
favor of marking the relevant driver API structs with the _subsystem
sentinel.

8328159b09 include: respect line limit in api pointer initialization
The automated process used to remove implicit casts resulted in code
that exceeded the documented line length limits.  Break the assignment
into two lines where this happened.

2e358f11d0 include/drivers: remove implicit casts from api pointer initialization
C++ disallows implicit cast of void pointers to a non-void pointer
type.  Presence of implicit casts prevents use of these headers in C++
applications.

Process: Run the following coccinelle script:

@@
identifier V;
identifier TAG =~ "driver_api";
type T;
expression E;
@@
 T* V =
+(T *)
 E->TAG;

in this command line from $ZEPHYR_BASE:

spatch --sp-file expcast.cocci \
   --include-headers --dir include/ --very-quiet \
 | sed -e '/^\+/s@\*) @*)@' \
 | (cd include/ ; patch -p1)

a2a7b776cb drivers: eeprom: add API for EEPROM devices
Add API for accessing Electrically Erasable Programmable Read-Only
Memory (EEPROM) devices.

EEPROMs have an erase block size of 1 byte, a long lifetime, and allows
overwriting data on byte-by-byte access.
