bf41e53e00 disk: disk_access: changed mutex for a spinlock
disk_access functions were called from an interupt context, thus
crashing on mutexes (no sleep is allowed in interrupt context).
The usage of a spinlock is permitted. The functions guarded by
the spinlock are executed very quickly anyway, so the spinlock
is applicable.

d18cbb60b2 drivers: disk: add DISK_IOCTL_CTRL_DEINIT command to supported IOCTLs
Add DISK_IOCTL_CTRL_DEINIT ioctl command to disk subsystem. When
disk_access_ioctl() is called with this command, the disk will be
de-initialized. After this IOCTL completes, the disk can safely be
reinitialized.

Fixes #60628

fb2d5c338b drivers: disk: add DISK_IOCTL_CTRL_INIT macro to initialize a disk
Add DISK_IOCTL_CTRL_INIT IOCTL to initialize a disk. This IOCTL is
intended to replace disk_access_init() for new applications, but
disk_access_init() is kept for legacy compatibility. The INIT IOCTL is
added to better match the path that will be used for disk
de-initialization. Like the disk_access_init() calls,
DISK_IOCTL_CTRL_INIT calls are reference counted

3386a43a51 disk_access: reference count initialization calls for disks
Reference count initialization calls for disks. This changes the
behavior of the disk_access_init() function, such that disks will no
longer be initialized again if the first disk access init call
succeeds.

Disk access is reference counted in preparation for supporting disk
de-initialization, where a balanced number of disk de-initialization
calls with disk initialization calls will de-initialize the disk.

Also, remove code in disk drivers that was already checking against
duplicate disk_access_init() calls.

Mutex and double-linked list can be statically initialized.

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.

2b5b7da9f3 subsys: disk: Add support for multiple disk interfaces
Add support for enabling multiple disk interfaces (Flash, RAM)
simultaneously in Zephyr by introducing a simple disk interface
framework where we can register multiple disks which would
interface with different storage devices. This would enable us
to have multiple instances of FATFS in Zephyr.

Add support for mass storage drive disk name which will be
used as an argument when calling the disk interface API's.

Enable multiple volumes support configuration in
ELM FAT library.
