Add driver support for xlnx SD/EMMC host controller. The driver
currently support SD host controller version 3.0 and EMMC host
controller version 5.1. This driver functions with the SDHC subsystem to
perform operations on device.
Driver support both interrupt and polled mode data transfer. Uses ADMA2
to perform data transfer.

Since the RA2L1 uses the macro "ICU_EVENT" instead of
"ELC_EVENT" (which is currently used) to input into
the IELSR register, the ek_ra2l1 board cannot assign
any interrupts for any driver.
This commit aim to correct the Event macro to input correct
value for IELSR register on all the Renesas SoC by using
"BSP_PRV_IELS_ENUM" macro.

Initialize the cyhal_sdio_config, such that the init
function won't do the pin configuration.
The gpios are setup using the zephyr pinctrl driver already.
Before the latest hal update the values were ignored and
the gpio configuration completely skipped.
But this is no longer the case and this commit
fixes that by setting the gpio pins to nc,
Also, explicitly set sdio_config.clock to NULL, to make
it clearer that the driver will check for that.

The driver should use resource type SDHC not SDIODEV.
In a older HAL version the value was not used as parameter
for clock initialization so it didn't matter, but breaks
the initialization of the driver with the latest hal.

The SD physical layer specification requires that the operating supply
be stable for at least 1 millisecond before providing the required 74
clocks. The maximum VDD ramp time is specified at 35ms, giving a total
minimum delay of 36ms.

This Kconfig has wrongly been added to defconfig files. It is not the
right place for it. It has never been the right place for it. Drivers
that need it should select the symbol in their Kconfig entries. Drop
PINCTL from Kconfig.defconfig and add proper select at Kconfig.sam*.

The imx USDHC driver previously queried the peripheral's internal card
detect signal to check card presence if no card detect method was
configured. However, some boards do not route the card detect signal and
do not work correctly with the DAT3 detection method supported by this
peripheral. As a fallback, assume the card is present in the slot but
log a warning to the user.

Rework CMD12 failure logic for SDHC SPI driver. Previously, the error
code of CMD12 was not checked, so even if CMD12 failed to send the
initial command would be retried. Change this behavior to retry CMD12
until it succeeds. If CMD12 fails, its error code will be propagated to
the caller. Otherwise, the return code from the command being sent by
the caller will be propagated.

Add basic functionality of Renesas SD/MMC driver. It can be used
for both gen3 and gen4 R-car boards, but tested only with H3ULCB,
Salvator XS M3 and Spider boards. This driver working with SDHC
subsystem.
The driver supports regularal reading/writing throught SD/MMC
controller buffer, DMA mode w/o interrupts and timing tuning.
Add gpio5 and sd0 nodes to h3ulcb and salvator xs which are needed
for working with SD cards. The GPIO node is needed for switching
voltage on SD card through gpio regulator driver.
Notes:
* the driver doesn't support SPI mode;
* SCC tuning and DMA mode based on IRQs are enabled by default;
* an address of a data buffer has to be aligned to 128 bytes if it
is not, driver will use non-DMA mode automatically;
* Renesas MMC DMAC doesn't support 64-bit DMA addresses, so for
case when we have 64-bit xref data address we use non-DMA mode;
* SD/MMC controller supports block size between 512 and 1 with
a lot of restrictions, more details you can find in code;
* support of HS400 mode isn't implemented inside driver.

This change marks each instance of the 'api' as 'static const'.
The rationale is that 'api' is used for declaring internal
module interfaces and is not intended to be modified at runtime.
By using 'static const', we ensure immutability, leading to usage of only
.rodata and a reduction in the .data area.

In sdhc_spi_response_get, the logic for slow cards previously only
retried reads 16 times. Instead of using this approach, read from the
card every 10 ms until the command timeout is reached or it responds.
This way, the command timeout will be respected for cards that do not
respond.
