Ok, let me rephrase.

The 8x74 pinctrl driver already contains this information.  It already 
defines a "blsp_spi8" group consisting of GPIOs 45, 46, 47, and 48.

This patch adds that same exact information into the device tree.  Why 
are we duplicating that information?  Why add it to the device tree when 
it's already in the driver (and already working).

Also, I don't see any code anywhere that uses these new device tree nodes.
