Some instances of the USDHC peripheral take longer to reset, and will
timeout with the previous delay of 100 cycles. Extend this delay to 1000
cycles to resolve this.

Remove function for waiting for clock gate, as this is not used anywhere
within the USDHC driver.

Some USDHC IP instances do not have the voltage control bit present, as
they can only operate at 3.3V. Move code to select 1.8V mode into a
separate helper, and guard the call to UDSHC_SelectVoltage() behind a
feature macro from MCUX SDK.

DDR50/DDR52 modes should use PINCTRL_STATE_SLOW (50MHz), so the lack of a
break statement after enabling DDR mode is expected. Add an explicit
__fallthrough to resolve the issue flagged by coverity scan

Explicitly set host_io fields, instead of using memset(). This way the
fields should have values that are defined in the enum types for each
field.

The iMX platform always uses pinctrl, there's no need to keep
extra macrology around pinctrl. Also updated driver's Kconfig to `select
PINCTRL`.

Change automated searching for files using "IRQ_CONNECT()" API not
including <zephyr/irq.h>.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Add SD response type masks, to allow drivers to mask out the
SPI or SD native mode response type based on the SD host controller
mode they use.

Implement SDHC driver for NXP USDHC peripheral, supporting all api calls
available in the sdhc driver. This implementation leverages NXP's HAL,
and simply implements a shim layer over the HAL itself.
