Subject: [PATCH 0/2] optee: register drivers on optee bus

Hello,

This patchset fixes issues with probing() tee, optee and optee driver
if they were compiled into kernel, built as modules or any mixed
combination.
These changes require optee-os changes which already were merged.
Main corresponding commits are:
https://github.com/OP-TEE/optee_os/commit/9389d8030ef198c9d7b8ab7ea8e877e0ace3369d
https://github.com/OP-TEE/optee_os/commit/bc5921cdab538c8ae48422f5ffd600f1cbdd95b2

optee_enumerate_devices() which discovers Trusted Applications on tee
bus is split up on 2 changes. Do probe of drivers which do not require
userspace support of tee-supplicant and stage two to run drivers with
support of tee-supplicant only after tee supplicant run. 

Best regards,
Maxim.

  optee: do drivers initialization before and after tee-supplicant run
