[PATCH v2 1/2] rpmsg: glink: smem: Use device name as IRQ name

[Chunkai Deng <chunkai.deng@oss.qualcomm.com>]

A SoC typically has multiple remoteprocs (ADSP, MPSS, CDSP, etc.), each
registering its own SMEM GLINK instance. With the static name "glink-smem"
all instances appear identically in /proc/interrupts, making it impossible
to associate an IRQ with a specific remote processor.

Pass dev_name(&smem->dev) to devm_request_irq() instead. The device name
is already set to "<parent>:<edge-node>" which uniquely identifies each
instance without requiring an additional field in the driver struct.
