Arnd Bergmann a8e9f5f672 Enable async communication with tee supplicant 
This pull request enables asynchronous communication with TEE supplicant
 by introducing meta parameters in the user space API. The meta
 parameters can be used to tag requests with an id that can be matched
 against an asynchronous response as is done here in the OP-TEE driver.
 
 Asynchronous supplicant communication is needed by OP-TEE to implement
 GlobalPlatforms TEE Sockets API Specification v1.0.1. The specification
 is available at https://www.globalplatform.org/specificationsdevice.asp.
 
 This change is backwards compatible allowing older supplicants to work
 with newer kernels and vice versa.
