Flash Update

The zl3073x driver implements support for flash update using the devlink-flash interface. It supports updating the device flash using a combined flash image ("bundle") that contains multiple components (firmware parts and configurations).

During the flash procedure, the standard firmware interface is not available, so the driver unregisters all DPLLs and associated pins, and re-registers them once the flash procedure is complete.

The driver does not support any overwrite mask flags.
