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).

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:

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.

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Rename DT_HAS_NODE to DT_HAS_NODE_STATUS_OKAY so the semantics are
clear. As going forward DT_HAS_NODE will report if a NODE exists
regardless of its status.

The check for label property is really checking to see if a device
exists and the better way to do that is to use DT_HAS_NODE(). Replace
refernces of DT_NODE_HAS_PROP(DT_INST(...), label) with
DT_HAS_NODE(DT_INST(...)).

Converts the sdhc spi driver to the new gpio api. Updates device trees
for the olimexino_stm32 and nrf52840_blip boards to set appropriate
active high/low polarity for the spi chip select pin.

We already returned out of the function if err is nonzero, therefore it
is impossible to reach this return statement.

This patch adds support for SDSCv1 and SDSCv2 cards. It has been tested
with 2 GiB SDSC and 4 GiB to 32 GiB SDHC cards from SanDisk.

The sdhc_cmd_r1_raw() function doesn't take into account the existence
of commands with data response. Because of this, some datas were being
lost.
The commands that return a r1 response and a data are: SDHC_SEND_CSD,
SDHC_SEND_CID, SDHC_READ_SINGLE_BLOCK, SDHC_READ_MULTIPLE_BLOCK,
SDHC_WRITE_BLOCK, SDHC_WRITE_MULTIPLE_BLOCK.
In order to solve this, was juts necessary skip the byte discard when
the command is one of these.
This problem was affecting, for example, the sdhc initialization. The
token returned from SDHC_SEND_CSD was being lost and the initialization
was broken.
Fixes#15444.

The name disk_access_sdhc.c is ambiguous,
actually this driver depends on SPI,
rename this file.
In addition, move the generic sdhc stuff from C file
to head file for other sdhc drivers to use.
1) disk_access_sdhc.c->disk_access_spi_sdhc.c.
2) create .h and move sdhc specifications from .c to .h.
