scm_call2 can block scm calls up to 2s due to its
retry mechanism whenever the secure firmware is
busy waiting for certain processing by the client
who in turn is waiting upon its scm call to either
complete or return with failure.
Upon early return, client can process the pending
requests to free up secure firmware and unblock
processing of all pending scm calls. Add a noretry
variant for scm_call2 which can be used by clients
who do not intend to wait for 2s for return status.

This is an implementation of para-virtualized SCM driver.
This driver is the FE. The BE is QCPE running in an hypervisor.
The FE driver forwards SCM calls over HAB to the BE.

Other processors/execution environments may support debug events. Implement
an 'smc instruction' based communications protocol and hook it up to
debugfs.

It is required on some hardware that the Limits Management
secure API be executed in mutual exclusion with certain
other hardware-accessing drivers. Provide a mutex to achieve
this.
