At present the GEM support in sifive_u machine is seriously broken. The GEM block register base was set to a weird number (0x100900FC), which for no way could work with the cadence_gem model in QEMU. Not like other GEM variants, the FU540-specific GEM has a management block to control 10/100/1000Mbps link speed changes, that is mapped to 0x100a0000. We can simply map it into MMIO space without special handling using create_unimplemented_device(). Update the GEM node compatible string to use the official name used by the upstream Linux kernel, and add the management block reg base & size to the <reg> property encoding. Tested with upstream U-Boot and Linux kernel MACB drivers.
