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.
Fixes: 5a5e9c0228e6 ("accel: Add Arm Ethos-U NPU driver")
