[PATCH] ASoC: cs35l56: Avoid static analysis warning of uninitialised variable

[Richard Fitzgerald <rf@xxxxxxxxxxxxxxxxxxxxx>]

From: Simon Trimmer <simont@xxxxxxxxxxxxxxxxxxxxx>

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.
