Subject: [PATCH v1 1/4] arm64: dts: colibri-imx8x: fix eval board pin configuration

From: Emanuele Ghidoli <emanuele.ghidoli@...adex.com>

Fix pinctrl groups to have SODIMM 75 only in one group.
Remove configuration of the pin at SoM level because it is normally
used as CSI_MCLK at camera interface connector.
Without this fix it is not possible, without redefining iomuxc pinctrl,
to use CSI_MCLK signal and leads to the following error messages:

imx8qxp-pinctrl scu:pinctrl: pin IMX8QXP_CSI_MCLK already requested
imx8qxp-pinctrl scu:pinctrl: pin-147 (16-003c) status -22

Fixes: 4d2adf738169 ("arm64: dts: colibri-imx8x: Split pinctrl_hog1")
