arm/aspeed: Rework NIC attachment The number of MACs supported by an Aspeed SoC is defined by "macs_num" under the SoC model, that is two for the AST2400 and AST2500 and four for the AST2600. The model initializes the maximum number of supported MACs but the number of realized devices is capped by the number of network device back-ends defined on the command line. This can leave unrealized devices hanging around in the QOM composition tree. To get virtual hardware that matches the physical hardware, you have to pass exactly as many -nic options as there are MACs, and some of them must be -nic none: * Machines ast2500-evb, palmetto-bmc, romulus-bmc, sonorapass-bmc, swift-bmc, and witherspoon-bmc: two -nic, and the second one must be -nic none. * Machine ast2600-evb: four -nic, the first one must be -nic none. * Machine tacoma-bmc: four nic, the first two and the last one must be -nic none. Modify the machine initialization to define which MACs are attached to a network device back-end using a bit-field property "macs-mask" and let the SoC realize all network devices. The default setting of "macs-mask" is "use MAC0" only, which works for all our AST2400 and AST2500 machines. The AST2600 machines have different configurations. The AST2600 EVB machine activates MAC1, MAC2 and MAC3 and the Tacoma BMC machine activates MAC2. Incompatible CLI change: -nic options now apply to *active* MACs: MAC1, MAC2, MAC3 for ast2600-evb, MAC2 for tacoma-bmc, and MAC0 for all the others. The machines now always get all MACs as they should.
