The original code tried to initialize PCA9541 without having the driver loaded. As result the initialization didn't take effect. Recently PCA9541 driver was added to the kernel and since then the initialization takes effect and has negatively impacted the platform stability. Commenting the initialization code out to restore the original behavior while analyzing further. Signed-off-by: Ying Xie <ying.xie@microsoft.com>
