From: Vignesh Raghavendra <vigneshr@xxxxxx>
Hook up required IO voltage regulators and drop no-1-8-v to support UHS
modes on SD cards.
Fixes: 5fc6b1b62639 ("arm64: dts: ti: Introduce AM62A7 family of SoCs")
Signed-off-by: Vignesh Raghavendra <vigneshr@xxxxxx>
[Judith: Remove no-1-8-v for sdhci2, keep otap-del-sel-legacy=0,
add fixes tag, reword commit]
