Patch 2,3,4 are accepted in this series and this one is only left. Bjorn, could you please help in picking this up if there are no further review comments. Thanks!

GENI(generic interface) based Qualcomm Universal Peripheral controller can support multiple serial interfaces like SPI,UART and I2C. Unlike other I2C controllers, QUP I2C bindings are present in parent schema. Move it out from parent to an individual binding and let parent refer to child schema later on. Please note, current schema isn't complete as it misses out few properties and thus, add these missing properties along the process.
