dt-bindings: mmc: samsung,exynos-dw-mshc: add specific compatible for exynos8890 (2025-09-23 16:45:04 +0200)

----------------------------------------------------------------
MMC core:
- Improve RPMB frame handling code
- Add support for a new max-sd-hs-hz DT property to limit frequency
- Add support to manage regulator-under-voltage events
- Support regulator-under-voltage for eMMC to mitigate data corruptions
- Add mmc_read_tuning() to allow a host to validate its tuning sequence
- Add some helpers to align checks for CMD23 support
- Read the CCCR register for SDIO over SPI rather than the unsupported CMD7

MMC host:
- Add COMPILE_TEST option for a couple of drivers
- Convert drivers to use the modern PM macros
- dw_mmc-exynos: Enable support for the Exynos8890 variant
- mmc_spi: Don't use crc ack during multiple block read
- renesas_sdhi: Enable 64-bit polling mode for R-Car gen3 and RZ/G2L SoCs
- rtsx_usb: Add support for over-current-protection
- sdhci-cadence: Add support for multi-block read gap tuning
- sdhci-msm: Add support for tuning for SDR50 mode for SD cards
- sdhci-msm: Enable support for the Lemans variant
- sdhci-pci: Disable SD card clock before update for a few Intel platforms
- sdhci-pxav3: Add support for UHS pinctrl settings
- tmio: Add 64-bit read/write support in polling mode

MEMSTICK:
- Convert to use timeouts to prevent indefinite waiting
- rtsx_usb: Add support for over-current-protection
