These are the reasons behind this patch submission:
1. if we don't support USB/AC charging don't enable it, saves
kernel resources and don't give user wrong idea about charging capabilities.
2. if a platform driver or any other chip can do USB/AC charging they will register with PS and
user/userspace will not get confused b/w two sysfs interfaces.

I will leave the decision the Anton.

Thanks,
Ram
