I'll see if I can fix that (Wolfson) in tonight's build - the wm8804 options aren't enabled in the new kernel.
Edit: I added WM8804 SPI and I2C as modules (these options are both new to 4.1) but I'm still seeing the same errors as you, so the dtb and/or driver may require a tweak - I've pinged @popcornmix. Hopefully this is an easy fix and doesn't have to go back to Hifiberry to make their driver compatible with the 4.1 kernel.
