[PATCH v2 5/8] arm64: dts: renesas: r9a09g057: Add support for enabling SDHI internal regulator

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

Add support for enabling SDHI internal regulator, by overriding the
status on the board DTS, when needed.

While at it, rename the gpio regulator label vqmmc_sdhi1->vqmmc_sdhi1_gpio
to avoid conflicts with internal regulator node names.
