ASoC: rt5682: Fix crash due to out of scope stack vars

Browse Source 
Move the declaration of temporary arrays to somewhere that won't go out
of scope before the devm_clk_hw_register() call, lest we be at the whim
of the compiler for whether those stack variables get overwritten.

Fixes a crash seen with gcc version 11.2.1 20210728 (Red Hat 11.2.1-1)

Fixes: edbd24ea1e ("ASoC: rt5682: Drop usage of __clk_get_name()")
