Move the securemsm-kernel uapi headers to a uapi include path,
to conform with the uapi requirements.
NOTE: Duplicating qcedev.h & smcinvoke.h temporarily until
clients that manually include the path use the exported headers.

Proxy map calls on a locked and already-mapped buffer should succeed.
Re-arrange state checks in retrieve_and_iommu_map() to ensure this.

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.
