Hi All,

This patch series aims to add SD/MMC support for Renesas RZ/V2H(P) SoC.

v4->v5
- Since the SDxIOVS and SDxPWEN pins can always be used as GPIO pins on
  the RZ/V2H(P) SoC dropped adding regulator support.

v3->v4
- Dropped 'renesas,sdhi-use-internal-regulator' property
- Defined vqmmc-regulator in top level
- For special handling of internal regulator now using of_device_is_available()
- Fixed comments from Claudiu
- Rebased patch on top of https://patchwork.kernel.org/project/linux-renesas-soc/patch/20240626085015.32171-2-wsa+renesas@sang-engineering.com/

v2->v3
- Renamed vqmmc-r9a09g057-regulator object to vqmmc-regulator
- Added regulator-compatible property for vqmmc-regulator
- Added 'renesas,sdhi-use-internal-regulator' DT property
- Included RB tags for patch 2/3
- Moved regulator info to renesas_sdhi_of_data instead of quirks
- Added support to configure the init state of regulator
- Added function pointers to configure regulator
- Added REGULATOR_CHANGE_VOLTAGE mask

v1->v2
- Dropped regulator core API changes
- Updated DT binding
- Now controlling PWEN bit via regulator api
