ASoC: cs35l56: Avoid static analysis warning of uninitialised variable
Static checkers complain that the silicon_uid variable passed by pointer to cs35l56_read_silicon_uid() could later be used uninitialised when calling cs_amp_get_efi_calibration_data(). cs35l56_read_silicon_uid() must have succeeded to call cs_amp_get_efi_calibration_data() and that would have populated the variable. However, initialise the value so we are not haunted by it forevermore.
