[PATCH 23/42] mmc: sdhci-of-bst: Use devm_of_reserved_mem_device_init_by_idx()

Use the devres-managed devm_of_reserved_mem_device_init_by_idx() instead
of the manual of_reserved_mem_device_init_by_idx()/
of_reserved_mem_device_release() pair, letting the device resource
manager handle cleanup automatically.
