Subject: [PATCH v2] iio: temperature: maxim_thermocouple: declare missing of table

Add missing <of_device_id> table for SPI driver relying on SPI
device match since compatible is in a DT binding or in a DTS.

Before this patch:
modinfo drivers/iio/temperature/maxim_thermocouple.ko | grep alias
alias: spi:max31855
alias: spi:max6675

After this patch:
modinfo drivers/iio/temperature/maxim_thermocouple.ko | grep alias
alias: spi:max31855
alias: spi:max6675
alias: of:N*T*Cmaxim,max31855C*
alias: of:N*T*Cmaxim,max31855
alias: of:N*T*Cmaxim,max6675C*
alias: of:N*T*Cmaxim,max6675

Heh oops I missed that somehow in initial development.

Applied to the togreg branch of iio.git. Given timing this may have
to wait for the next cycle to go upstream.

Thanks.
