From: Allen Pais <apais@xxxxxxxxxxxxxxxxxxx>
The following out of memory errors are seen on kexec reboot
from the optee core.
[ 0.368428] tee_bnxt_fw optee-clnt0: tee_shm_alloc failed
[ 0.368461] tee_bnxt_fw: probe of optee-clnt0 failed with error -22
tee_shm_release() is not invoked on dma shm buffer.
Implement .shutdown() in optee core as well as bnxt firmware driver
to handle the release of the buffers correctly.

optee: fix tee out of memory failure seen during kexec reboot
