arm64: dts: imx8mm-venice: fix spi2 pin configuration

BugLink: https://bugs.launchpad.net/bugs/1978234
commit dc900431337f5f861e3cc47ec5be5a69db40ee34 upstream.

Due to what looks like a copy-paste error, the ECSPI2_MISO pad is not
muxed for SPI mode and causes reads from a slave-device connected to the
SPI header to always return zero.

Configure the ECSPI2_MISO pad for SPI mode on the gw71xx, gw72xx and
gw73xx families of boards that got this wrong.
