If the server dies, the memobj would be released two times.
Assuming, one instance is already held by the server which
is not true.

If invoke call fails due to some reason, map objects created
for memory objects should also be released. Failing to do so,
creates a memory leak as TZ is unaware of these objects and
no one calls release on these.

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.
