anolis: sw64: sound: fix compile error when CONFIG_SND_DUMMY=y 

ANBZ: #4688

In a previous commit, #include <linux/io.h> was added
inside a function, which caused compilation errors.
To resolve this issue, the header file has been moved
to the beginning of the file to ensure successful compilation.

This change does not affect functionality and is purely a fix
for the compilation error.

Fixes: ce16ff1a7368 ("anolis: sw64: sound: avoid pagefault in pcm driver's memset")
