Subject: dm: core: Extend struct udevice by '.uclass_platdata' field.
This commit adds 'uclass_platdata' field to 'struct udevice', which
can be automatically allocated at bind. The allocation size is defined
in 'struct uclass_driver' as 'per_device_platdata_auto_alloc_size'.
New device's flag is added: DM_FLAG_ALLOC_UCLASS_PDATA, which is used
for memory freeing at device unbind method.
As for other udevice's fields, a complementary function is added:
- dev_get_uclass_platdata()
