[PATCH v2] ASoC: SOF: imx: Fix devm_ioremap_resource check

[Daniel Baluta <daniel.baluta@nxp.com>]

devm_ioremap_resource does not return NULL on error
but an error pointer so we need to use IS_ERR to check
the return code.

While at it also pass the error code to dev_err_probe
to improve logging.

Fixes: bc163baef570 ("ASoC: Use of_reserved_mem_region_to_resource() for "memory-region"")
