The ID table already has respective entry and MODULE_DEVICE_TABLE and
creates proper alias for platform driver. Having another MODULE_ALIAS
causes the alias to be duplicated.

The spi-altera driver has two flavors: platform and dfl. I'm seeing
a case where I have both device types in the same machine, and they
are conflicting on the SPI ID:
... kernel: couldn't get idr
... kernel: WARNING: CPU: 28 PID: 912 at drivers/spi/spi.c:2920 spi_register_controller.cold+0x84/0xc0a
Both the platform and dfl drivers use the parent's driver ID as the SPI
ID. In the error case, the parent devices are dfl_dev.4 and
subdev_spi_altera.4.auto. When the second spi-master is created, the
failure occurs because the SPI ID of 4 has already been allocated.
Change the ID allocation to dynamic (by initializing bus_num to -1) to
avoid duplicate SPI IDs.

In preparation of adding support for a new bus type,
separate the core spi-altera code from the platform
driver code.
