Subject: [PATCH] ARM: dts: kswitch-d10: use open drain mode for coma-mode pins

The driver use the coma-mode pins as open-drain. Flag them in the device
tree accordingly. This avoids the following error:
[   14.114180] gpio-2007 (coma-mode): enforced open drain please flag it properly in DT/ACPI DSDT/board file

Fixes: 46a9556d977e ("ARM: dts: kswitch-d10: enable networking")
