soundwire: amd: Fix a check for errors in probe()

Browse Source 
This code has two problems:
1) The devm_ioremap() function returns NULL, not error pointers.
2) It's checking the wrong variable.  ->mmio instead of ->acp_mmio.

Fixes: d8f48fbdfd ("soundwire: amd: Add support for AMD Manager driver")
