Patch cherry-picked from the following location: https://chromium-review.googlesource.com/#/c/269931/ Disable the i2c device on gsbi4 and mark gsbi4_h and gsbi4_qup clks as unused. If they are enabled, clock framework will turn them off at end of probe. On ipq806x by design gsbi4_qup, gsbi4_h clks and i2c on gsbi4 are meant for RPM usage. So turning them off in kernel is incorrect. Signed-off-by: Mathieu Olivari <mathieu@codeaurora.org> SVN-Revision: 45728
