Series [v2] arm64: dts: renesas: v2mevk2: Add uSD card and eMMC support |

Commit Message

  The RZ/V2M EVK comes with a slot for a uSD card, and an eMMC.
Add support for the both of them.

Please note that the pinctrl driver for RZ/V2M doesn't support
interrupts yet, therefore the card detect pin has been connected
to the SDHI IP directly in this patch.
We'll connect the card detect pin to its corresponding GPIO when
we'll have driver support for interrupts in the RZ/V2M pinctrl
driver.

No underscores in node names.
