ASoC: amd: change clk_get() to devm_clk_get() and add missed checks
cz_da7219_init() does not check the return values of clk_get(),
while da7219_clk_enable() calls clk_set_rate() to dereference
the pointers.
Add checks to fix the problems.
Also, change clk_get() to devm_clk_get() to avoid data leak after
failures.
Fixes: bb24a31ed584 ("ASoC: AMD: Configure wclk and bclk of master codec")
