platform: introduce module id table for platform devices
Now platform_device is being widely used on SoC processors where the
peripherals are attached to the system bus, which is simple enough.
However, silicon IPs for these SoCs are usually shared heavily across
a family of processors, even products from different companies. This
makes the original simple driver name based matching insufficient, or
simply not straight-forward.
Introduce a module id table for platform devices, and makes it clear
that a platform driver is able to support some shared IP and handle
slight differences across different platforms (by 'driver_data').
Module alias is handled automatically when a MODULE_DEVICE_TABLE()
is defined.
To not disturb the current platform drivers too much, the matched id
entry is recorded and can be retrieved by platform_get_device_id().
