[PATCH v2 07/12] spi: s3c64xx: let the SPI core determine the bus number

[Tudor Ambarus]

Let the core determine the bus number, either by getting the alias ID
(as the driver forces now), or by allocating a dynamic bus number when
the alias is absent. Prepare the driver to allow dt aliases to be
absent.
