Subject: [PATCH 01/11] platform: early: provide early_platform_add_device()

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

Currently we only have early_platform_add_devices() which takes struct
platform_device ** as argument, requiring the users to have an
intermediate array of platform_device pointers even if we're only
adding a single device. Provide a helper for adding a single device at
a time.
