[PATCH 3/3] dmaengine: rcar-dmac: Remove redundant dev_err()/dev_err_probe()

[Wolfram Sang <wsa+renesas@sang-engineering.com>]

From: Pan Chuang <panchuang@vivo.com>

The devm_request_threaded_irq() now automatically logs detailed error
messages on failure. This eliminates the need for driver-specific
dev_err() and dev_err_probe() calls that previously printed generic
messages.
