4.4-stable review patch. If anyone has any objections, please let me know.

From: Amit Pundir <amit.pundir@linaro.org>
commit 7dc5fe0814c35ec4e7d2e8fa30abab72e0e6a172 upstream.
AOSP use userspace firmware loader to load firmwares, which will return -EAGAIN in case qca/rampatch_00440302.bin is not found. Since there is no rampatch for dragonboard820c QCA controller revision, just make it work as is.
