Add the base of the SMMU proxy driver for Android. The proxy driver
will take memory from the PVM, share it with the TVM and map it into
an S1 context bank on the TVM, before returning an IOVA for the mapped
buffer.
This patch intended to create the driver to allow other kenrel modules
to compile against it.

req_done is usually scheduled on success scenarios as
it needs to wakeup the sleep thread. However, in the
scenario where sleep has timed out, there is nothing to
wake up, and req_done can be called sequentially instead
of scheduling it (which might cause use after free).
Test: OEMCrypto tests.

This change makes changes to smcinvoke driver to handle suspend and resume
scenarios. If the accept thread gets interrupted, do not set the server state
as defunct if the thread is in freezing state, i.e. if the thread is going in
suspend. In such cases, increase timeout of that server so that invoke thread
waits indefinitely for response from userspace until the system resumes back.
Tests:
1. Stability testing has been done on kalama.
2. smcinvoke vendor client testing is done on pineapple.

Change consists creation of ADCI thread at SMCInvoke
driver initialization
Change consists creation of ADCI thread at SMCInvoke driver initialization
Following scenario have been tested for this change
(1) ADCI thread creation and QTEE invocation during driver initialization
(2) Backward Compatibility - IF ADCI feature is not supported (OBJECT_ERROR_INVALID)
then exit the ADCI thread gracefully after cleaning up all the resources
(3) Leak Test: All the resources held by ADCI thread should be released if ADCI feature
is not supported by QTEE
(i) adci task_struct state and exit state:
state = TASK_RUNNING , exit_state = 0 (While ADCI thread execution)
state = TASK_DEAD , exit_state = EXIT_DEAD (During ADCI thread termination)
(ii) adci task_struct = NULL (fetched based on adci thread_id) which make sure
task_struct has been deallocated
(4) SMCInvoke related Test: All the internal(suuported),memobj and cbo testing has been performed.
