cores: Remove shutdown function from spi_core_3000

This effectively reverts 0433e74. The set_shutdown() and get_shutdown()
API calls do not have a counterpart in simple_spi_core.v, which is
typically the HDL endpoint for this core driver, and thus could write to
a non-existent register. They are also never used in UHD, nor are they
part of the spi_iface interface.
