spi: s3c64xx: add the BROKEN_CS case when setting up the transfer
The CS line might be disconneced ("broken"), therefore unused.
In this case, the device doesn't need to wait for the user to
handle the CS line for selecting the slave. The data will then be
automatically transferred without taking the CS line status into
account.
