This commit expands RPC support for the OP-TEE driver using 2 files:
1) drivers/misc/optee_rpc.c
* Add support for RPCs that can be handled directly by the kernel.
* Can delegate RPC handling to optee_supplicant.c for RPCs that
need userspace interaction.
2) drivers/misc/optee_supplicant.c
* Enable communication between the userspace TEE supplicant and the
kernel driver.
Additional changes were needed to the following files:
1) drivers/misc/optee.c
* Add ioctls used SOLELY by the userspace TEE supplicant.
* Register /dev/teepriv0 if the supplicant is enabled in Kconfig
* Add OPTEE_ROLE_CA and OPTEE_ROLE_SUPPLICANT conditionals to
differentiate paths, between a normal Client Application (CA)
and the TEE supplicant.
* Change some functions from static to "public" to reuse them
in other C files.
* Adjust optee_to/from_msg_param() to work with RPCs.
2) drivers/misc/optee_smc.c
* Call the RPC handler from optee_rpc.c
3) drivers/misc/optee_msg.h
* Add definition needed for RPCs
4) drivers/misc/tee.h
* Add ioctl definitions
* Add TEE_SHM_SUPP flag, checked when unregistering supplicant
memory.
5) Documentation/guides/optee.rs
* Add documentation for RPCs and the supplicant.
6) drivers/misc/{CMakeLists.txt, Make.defs}
* Account for the new files.
7) drivers/misc/Kconfig
* Add DEV_OPTEE_SUPPLICANT option to enable/disable the supplicant
driver.
