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

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.

Fixes: bc163baef570 ("ASoC: Use of_reserved_mem_region_to_resource() for "memory-region"")
Signed-off-by: Daniel Baluta <daniel.baluta@....com>
