SSBI: Remove MSM_ prefix from SSBI drivers
Although the SSBI sub is currently only used on MSM SoCs, it is still a bus in its own right. Remove this msm_ prefix from the driver and it's symbols. Clients can now refer directly to ssbi_write() and ssbi_read(). Signed-off-by: David Brown <davidb@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
