Subject: [PATCH 05/10] arm64: dts: imx8mp-hummingboard-pulse/cubox-m: fix
 vmmc gpio polarity

Fix the polarity in vmmc regulator node for the gpio from active-high to
active-low. This is a cosmetic change as regulator default to active-low
unless property enable-active-high was also specified - ignoring the
flag on gpio handle.

Fixes: a009c0c66ecb ("arm64: dts: add description for solidrun imx8mp som and cubox-m")
Fixes: 2a222aa2bee9 ("arm64: dts: add description for solidrun imx8mp hummingboard variants")
