accel/ethosu: check MMIO mapping errors in probe

devm_platform_ioremap_resource() returns an error pointer when the register
resource cannot be mapped. ethosu_probe() stores it and continues until
initialization dereferences it through MMIO accessors.

Return the mapping error before initializing the device.
