core: secure storage: dual filesystems support
Adds support for multiple filesystems by keeping a pointer to
tee_file_operations in the tee_pobj and tee_storage_enum structures.
Two identifiers are added to the API to be used as the storage_id
parameter, so that TAs may dynamically choose the filesystem:
- TEE_STORAGE_PRIVATE_REE (requires CFG_REE_FS=y)
- TEE_STORAGE_PRIVATE_RPMB (requires CFG_RPMB_FS=y)
The value TEE_STORAGE_PRIVATE will select the REE FS if available,
otherwise RPMB. At least one FS has to be enabled at build time. Only
the REE filesystem is enabled by default.
