Zephyr already has a directory for storage API relevant headers.
Move disk_access.h header to include/storage where it fits better
structurally.

The files disk_access_usdhc.c, disk_access_spi_sdhc.c,
disk_access_stm32_sdmmc.c, disk_access_ram.c and
disk_access_flash.c are actually drivers for block devices and SD/MMC
controllers. This patch moves this drivers to drivers/disk and
reworks the configuration so that the drivers are selected when
the corresponding node is enabled.

This is another API that is being used in all timer drivers and is not
internal to the clock subsystem. Remove the leading z_ and make promote
it to a cross-subsystem API.

The SD Card Physical Layer specification states in Table 7-1
(in section 7.3.1.1) that the LSB of the 48 bit command must
be set to 1 to act as an 'end bit'.

This commit prepares supporting sdmmc on
stm32l4+ devices. When trying to compile the
sdmmc driver there is a compilation error
because `HAL_SDEx_DriveTransceiver_1_8V_Callback`
is not implemented. We solve this by compiling
also `sd_ex` in cube as this function is implemented
there as weak.

Convert from device_get_binding to DEVICE_DT_GET. In doing this we
no longer need the label in the devicetree node so we remove that.
Removed all __ASSERT_NO_MSG(clk) since we'll get a build error if
DEVICE_DT_GET cant be satisfied, and the clock control api's will
handle reporting if the device_is_ready.

Now that we generate a header that extern's all possible devicetree
based device struct we can remove DEVICE_DT_DECLARE and
DEVICE_DT_INST_DECLARE as they aren't needed anymore.

For USB mass storage class, a fixed size 16 KiB FAT12 ramdisk
is forced. This is not really visible to the user and
the DISK_RAM_VOLUME_SIZE option is ignored.
There is no use of such a small file system and for USB MSC
testing, like throughput or USB3CV, a file system is not necessary.

The power and chip detect gpios are optional device tree properties for
the nxp usdhc driver. Fixes a build error on the mm_swiftio board, which
does not set the power gpio property.

Replace all calls to the assert macro that comes from libc by calls to
__ASSERT_NO_MSG(). This is usefull as the former might be different
depending on the libc used and the later can be customized to reduce
flash footprint.

The sdhc_spi_write_multi function is sending the CMD25
for multiple block write operation on the SD card
instead of looping the CMD24. This is improving
the transfer speed compared to the sdhc_spi_write function
when the nb of blocks to write is significant (more than 2).

Leave the SPI CS GPIO handling to the SPI controller driver and make SPI
CS GPIO optional for SDHC disk access via SPI.
The SPI SDHC implementation relies on SPI_HOLD_ON_CS so we need to
explicitly release the SPI controller driver after ending transmissions
to force the CS line to be de-asserted.
Fixes#27444.

This set of functions seem to be there just because of historical
reasons, stemming from Kbuild. They are non-obvious and prone to errors,
so remove them in favor of the `_ifdef()` ones with an explicit
`CONFIG_` condition.
Script used:
git grep -l _if_kconfig | xargs sed -E -i
"s/_if_kconfig\(\s*(\w*)/_ifdef(CONFIG_\U\1\E \1/g"
