[PATCH v2 01/11] next-cube.c: add dummy Ethernet register to allow diagnostic to timeout

[Mark Cave-Ayland]

Add a dummy register at address 0x6000 in the MMIO memory region to allow the
initial diagnostic test to timeout rather than getting stuck in a loop
continuously writing "en_write: tx not ready" to the console.
