dpll: zl3073x: Add firmware loading functionality

Add functionality for loading firmware files provided by the vendor
to be flashed into the device's internal flash memory. The firmware
consists of several components, such as the firmware executable itself,
chip-specific customizations, and configuration files.

The firmware file contains at least a flash utility, which is executed
on the device side, and one or more flashable components. Each component
has its own specific properties, such as the address where it should be
loaded during flashing, one or more destination flash pages, and
the flashing method that should be used.
