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.
