cnss: Sysfs support to test BMI Commands 



QCA6180 supports various BMI commands which are not needed for
the wlan BMI Phase.
To verify all the BMI Commands add support to test them on need.

Test: echo 0x09 to fw_image_setup to enable bmi testing.

Commands:
BMI_NO_COMMAND, BMI_WRITE_MEMORY, BMI_READ_MEMORY,
BMI_EXECUTE, BMI_GET_TARGET_INFO, BMI_DONE
