[PATCH 5/9] tee: optee: probe successfully even when no devices are found

[Sascha Hauer]

OP-TEE iterates over the devices and when none are found the OP-TEE
driver returns with an error. Return successfully instead because
for example RPMB support doesn't require any devices exported from
OP-TEE.
