spi_master: Add shutdown function in spi_master struct

With this, register_spi_master can take care of register_shutdown
as well, and every spi master only needs to call register_spi_master
instead of calling both register_spi_master and register_shutdown.

Testing:
In dummyflasher, comment out free(data) in shutdown. Test fails with error:
../dummyflasher.c:949: note: block 0x55e0727a6e40 allocated here
ERROR: dummy_init_and_shutdown_test_success leaked 1 block(s)
Means, shutdown function is invoked for drivers with "old" API
(so, transitioning from old to new API is not breaking anything).

Next patches in the chain converts spi masters to use new API.
