core: arm: stmm_sp: fix calls to tee_pobj_get()

Fixes calls to tee_pobj_get() that use boolean value false as argument
where an enum tee_pobj_usage argument is expected.

Between OP-TEE release tags 2.4.0 and 3.11.0, tee_pobj_get() used to
take a boolean @temporary argument. The function prototype changed in
commit 6885abf ("core: tee_pobj_get() takes an enum tee_pobj_usage")
and was merged in release tag 3.11.0 but initial implementation of StMM
support [1] and its related source file renaming [2] sadly used the
old prototype, using false (0) instead of TEE_POBJ_USAGE_OPEN (0).

Fixes: 42471ec ("core: load stmm via secure partition") [1]
Fixes: f9cd31c ("core: rename secure_partition to stmm_sp") [2]
