ASoC: amd: change clk_get() to devm_clk_get() and add missed checks

[ Upstream commit 95d3befbc5e1ee39fc8a78713924cf7ed2b3cabe ]

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.
