serial: 8250_dw: Avoid double error messaging when IRQ absent
Since the commit 7723f4c5ecdb ("driver core: platform: Add an error message
to platform_get_irq*()") platform_get_irq() started issuing an error message.
Thus, there is no need to have the same in the driver
Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")
