arm/aspeed: rainier: Add i2c eeproms and muxes

Browse Source 
These are the devices documented by the Rainier device tree. With this
we can see the guest discovering the multiplexers and probing the eeprom
devices:

 i2c i2c-2: Added multiplexed i2c bus 16
 i2c i2c-2: Added multiplexed i2c bus 17
 i2c i2c-2: Added multiplexed i2c bus 18
 i2c i2c-2: Added multiplexed i2c bus 19
 i2c-mux-gpio i2cmux: 4 port mux on 1e78a180.i2c-bus adapter
 at24 20-0050: 8192 byte 24c64 EEPROM, writable, 1 bytes/write
 i2c i2c-4: Added multiplexed i2c bus 20
 at24 21-0051: 8192 byte 24c64 EEPROM, writable, 1 bytes/write
 i2c i2c-4: Added multiplexed i2c bus 21
 at24 22-0052: 8192 byte 24c64 EEPROM, writable, 1 bytes/write
