spi: Fix modalias for ACPI enumerated SPI devices

There is a minor fault about ACPI enumerated SPI devices with their modalias attribute. Now modalias is set by device instance not by hardware ID. For example "spi:INTABCD:00", "spi:INTABCD:01" etc.

This means each device instance gets different modalias which does match with generated modules.alias. Currently this is not problem as matching can happen also with "acpi:INTABCD" modalias.

Fix this by using ACPI hardware ID.

Applied, thanks.
