Subject: [PATCH] arm64: dts: renesas: rzv2mevk2: Fix eMMC/SDHI pinctrl names

The original commit uses the same names ("data" and "ctrl")
for the subnodes of pinctrl definitions for both eMMC and
SDHI0 (emmc_pins, sdhi0_pins, and sdhi0_pins_uhs) leading to
the below issue:

pinctrl-rzv2m b6250000.pinctrl: pin P8_2 already requested by 85000000.mmc; cannot claim for 85020000.mmc
pinctrl-rzv2m b6250000.pinctrl: pin-130 (85020000.mmc) status -22
renesas_sdhi_internal_dmac 85020000.mmc: Error applying setting, reverse things back

This commit fixes the problem by making the names for the
pinctrl subnodes of eMMC and SDHI0 unique.

Fixes: b6c0be722b0c ("arm64: dts: renesas: rzv2mevk2: Add uSD card and eMMC support")
