The name "spi" is reserved for nodes representing an SPI controller.
Rename the "spi" pinmux group to "spi-miso" to avoid the issue and for
consistency with other pinmux groups.

Rob,

do you think perhaps DTC is being a little too strict here? Seems to me
like the check could be limited to nodes that have a name and a unit
address, the assumption being that an SPI controller would always have
some sort of register space that requires a reg property and therefore
also a unit address.

Thierry

The name "spi-miso" is wrong since it also has spi-mosi...
