drivers/base: Introduce device_match_t for device finding APIs
There are several drivers/base APIs for finding a specific device, and
they currently use the following good type for the @match parameter:
int (*match)(struct device *dev, const void *data)
Since these operations do not modify the caller-provided @*data, this
type is worthy of a dedicated typedef:
typedef int (*device_match_t)(struct device *dev, const void *data)
Advantages of using device_match_t:
- Shorter API declarations and definitions
- Prevent further APIs from using a bad type for @match
So introduce device_match_t and apply it to the existing
(bus|class|driver|auxiliary)_find_device() APIs.
