[PATCH 42/42] ASoC: sprd: Use devm_of_reserved_mem_device_init()

[Mukesh Ojha <mukesh.ojha@oss.qualcomm.com>]

Use the devres-managed devm_of_reserved_mem_device_init() to ensure
the reserved memory region is released on device removal, fixing a
missing cleanup — the driver has no remove function. Also drop the
now-unused local variable np.
