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.
