[PATCH] firmware: stratix10-svc: Fix a potential resource leak in svc_create_memory_pool()

[Dinh Nguyen <dinguyen@kernel.org>]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

svc_create_memory_pool() is only called from stratix10_svc_drv_probe().
Most of resources in the probe are managed, but not this memremap() call.

There is also no memunmap() call in the file.

So switch to devm_memremap() to avoid a resource leak.
