From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

This function can extract all the information it needs from struct
qce_device alone so simplify its arguments. This is done in preparation
for adding support for register I/O over DMA which will require
accessing even more fields from struct qce_device.
