opaque_master: Use new API to register shutdown function

This allows opaque masters to register shutdown function in
opaque_master struct, which means there is no need to call
register_shutdown in init function, since this call is now a part
of register_opaque_master.

As a consequence of using new API, two things are happening here:
1) No resource leakage anymore in case register_shutdown() would fail,
2) Fixed propagation of register_opaque_master() return values.

BUG=b:185191942
TEST=1) builds and ninja test including CB:56413
2) on ARMv7 device
flashrom -p linux_mtd -V
-> using linux_mtd, chip found
