remoteproc: qcom_wcnss: Fix reserved region mapping failure
Commit c70b9d5fdcd7 ("remoteproc: qcom: Use of_reserved_mem_region_*
functions for "memory-region"") switched from devm_ioremap_wc() to
devm_ioremap_resource_wc(). The difference is devm_ioremap_resource_wc()
also requests the resource which fails. Testing of both fixed and
dynamic reserved regions indicates that requesting the resource should
work, so I'm not sure why it doesn't work in this case. Fix the issue by
reverting back to devm_ioremap_wc().
