Problem:
TEE logs are output to UART and not via kmsg.
Secure OS should support routing TEE logs into kmsg.

2) add API to support routing TEE logs to REE kmsg.

and the module not depend to kernel, which may introduce very strange
errors, and it customize toolchain and configures, which made the system
very hard to maintain.

Rewrite the makefile and structure for the above problem
This CL also support build on Q

PD#OTT-3799
Problem:
This bug occurs when:
- a new request arrives, one thread(let's call it A) is pending in
optee_supp_req() with req->busy is initial value false.
- tee-supplicant is killed, then optee_supp_release() is called, this
function calls list_del(&req->link), and set supp->ctx to NULL. And
it also wake up process A.
- process A continues, it firstly checks supp->ctx which is NULL,
then checks req->busy which is false, at last run list_del(&req->link).
This triggers double list_del() and results kernel panic.
Solution:
For solve this problem, we rename req->busy to req->in_queue, and
associate it with state of whether req is linked to supp->reqs. So we
can just only check req->in_queue to make decision calling list_del()
or not.
