Why enable this here but not any of the i2c/spi/uart devices that are a
child? Can this hunk be split off to a different patch?


Currently there is no usecase on qup1 and hence not enabled.
Regarding splitting this, I did not get the exact reason why we need to split. This patch adds all the qup wrapper1 nodes and we are enabling it in board file.

status = "okay";
