[Buildroot] [git commit] package/optee-client: add option to configure TEE-based storage location

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=96929f344ff6ad2eb8311933d3a8a69a2be02882
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

OP-TEE provides the possibility of secure storage done by the
normal world OS via tee-supplicant.

The location is a compile-time value and by default it is /data/tee .
As this might not be suitable for all use-cases add an option to
set the CFG_TEE_FS_PARENT_PATH compile option.

Default value is still /data/tee as it was before adding this option.
