[PATCH v3 04/16] driver core: platform: Include header for struct platform_device_id

[Uwe Kleine-König (The Capable Hub)]

Platform drivers can define an array containing the supported device
variants to be assigned to the struct platform_driver's .id_table.

While a forward declaration of struct platform_device_id is technically
enough to make the driver self-contained, it's reasonable to provide the
(very lightweight) data type definition for that array in
<linux/platform_device.h> to not add that burden to all platform drivers
with an id-table.

Note that currently <linux/device.h> transitively includes
<linux/mod_devicetable.h> that provides struct platform_device_id. But
that include is planned to be replaced by a tighter set of includes that
only define the structures relevant for the stuff in <linux/device.h>.
