[PATCH v2 01/11] firmware: qcom: move Qualcomm code into its own directory

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

We're getting more and more qcom specific .c files in drivers/firmware/
and about to get even more. Create a separate directory for Qualcomm
firmware drivers and move existing sources in there.
