dpll: zl3073x: Implement devlink flash callback
Use the introduced functionality to read firmware files and flash their
contents into the device's internal flash memory to implement the devlink
flash update callback.
Sample output on EDS2 development board:
# devlink -j dev info i2c/1-0070 | jq '.[][]["versions"]["running"]'
{
"fw": "6026"
}
# devlink dev flash i2c/1-0070 file firmware_fw2.hex
