Upstream prefers existing drivers be converted to support multiplatform kernels. This requires drivers to be located in generic functionality directories instead of specific mach directories. Move the smd and smsm drivers to the drivers/soc/qcom location to support multiplatform. Change-Id: I7f2e990341f0f34e336e71bd3b06a7c2a46d8bc1 Signed-off-by: Jeffrey Hugo <jhugo@codeaurora.org>
