Cover letter [PATCH v3 0/2] PSP TEE driver update and bug fixes

The first patch helps to improve the response time by reducing the polling time of the tee command status variable.

Second patch is a bug fix to handle multi-threaded use-case. During testing, race condition was seen due to missing synchronisation in writes to the TEE ring buffer. This patch helps to resolve that.

v3:
* Fixed checkpatch.pl warning

v2:
* Updated copyright year as a part of code change
