ASoC: cs35l56: Abort TDM mask loop at maximum channel shift

Browse Source 
Exit the for_each_set_bit() loop in cs35l56_make_tdm_config_word() after
all possible channel shifts have been done. This prevents going around
the loop with out-of-range shift values, which is technically undefined
behaviour. It also shuts up code analysis tools.
