[PATCH v2 26/37] dm: core: Move flags to device-runtime info

[Simon Glass]

When of-platdata-inst is active, use the flags in the new udevice_rt
table, dropping them from the main struct udevice. This ensures that the
latter is not updated at runtime.

Changes in v2:
- Leave the flags_ memeber in the same struct position
