[PATCH] ASoC: amd: Return ENODEV if acp63 is not found.

[Tom Rix <trix@redhat.com>]

The clang build fails with
sound/soc/amd/ps/pci-ps.c:218:2: error: variable 'ret' is used
  uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized]
        default:
        ^~~~~~~

When no device is found -ENODEV should be returned.
A switch with a single case is overkill, change to if-else.

Fixes: 1d325cdaf7a2 ("ASoC: amd: ps: refactor platform device creation logic")
