From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

Extend hardware support on Renesas RZ/T2H and RZ/N2H SoCs and evaluation
boards. Below are the features added for the RZ/T2H and RZ/N2H SoCs and
EVKs:
- Enable I2C0 and I2C1 support
- Enable EEPROM on I2C0
- Enable LEDs on RZ/T2H and RZ/N2H EVKs.
- Enable MMC on RZ/T2H and RZ/N2H EVKs.
- Enable MicroSD card slot on RZ/T2H and RZ/N2H EVKs.
- Enable SD card slot on RZ/T2H and RZ/N2H EVKs.

Note, patches apply on top of [0]
[0] https://web.git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-devel.git/log/?h=renesas-dts-for-v6.18

- Added Reviewed-by tag from Geert
- Changed led node names
- Added color/function/function-enumerator properties
- Replaced GPIO_ACTIVE_LOW with GPIO_ACTIVE_HIGH
- Moved header file inclusions to common dtsi
- Updated switch settings for led-9
- Replaced RZN2H_PORT_PINMUX with RZT2H_PORT_PINMUX
- Corrected switch settings for I2C1
- Added comment regarding DSW17 settings
- Dropped sd0-emmc-prefixes
