Freeze at boot. intel-lpss is trying to synchronously load idma64 module
in asynchronous conext.

Let userspace load the module to avoid the deadlock.

Users confirmed the proposed fix can solve the issue.

[Where problems could occur]
Userspace can handle modules loading just fine, so there shouldn't be
any surprise.
