Move all initialisation of the data struct to the init function to avoid
creating the very large `struct sd_card` in `.bss`.

Remove CONFIG_SDMMC_VOLUME_NAME, and set the disk name based on the
``disk-name`` property. This aligns with other disk drivers, and allows
for multiple instances of the sdmmc_subsys disk driver to be registered.
Add disk-name properties for all in tree definitions for the
sdmmc-subsys disk driver, and change all in tree usage of the disk name

Power off the SD card in `DISK_IOCTL_CTRL_DEINIT`, instead of only
waiting for the card to be idle then doing nothing. This is a safer
state for `DISK_IOCTL_CTRL_DEINIT`, which is documented as preparing the
disk to be removed from the system. It also has the advantage of
lowering power consumption while de-initialized.

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.

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

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.
