Adds a user buffer to tee_invoke_supp_plugin_rpc() so direct user memory
access can be used when called with a buffer in user memory instead of
core memory. tee_invoke_supp_plugin_rpc() can still take a core memory
buffer as an argument if needed.
PTA_SYSTEM_SUPP_PLUGIN_INVOKE in the system PTA is updated to pass the
memref as a user memory buffer instead of a core memory buffer.
This fixes a direct privileged memory access to user space memory.
Fixes: 4e154320e47c ("core: Apply finer-grained PAN")
