ASoC: txx9aclc_ac97: Fix kernel crash on probe
commit 9febd494d15c4a351e9c9cae7184643144eea892 upstream.
This patch fixes a crash caused by commit 3bed3344c826
(ASoC: txx9aclc_ac97: Convert to devm_ioremap_resource()).
This is an attempt to assign "drvdata->base" while memory
for "drvdata" is not already allocated.
