[PATCH v4 08/12] ARM: dts: aspeed: anacapa: Enable MCTP and FRU for NIC

[Colin Huang via B4 Relay]

From: Andy Chung <Andy.Chung@xxxxxxx>

Add the mctp-controller property to enable frontend NIC management
via PLDM over MCTP.
Also add EEPROM device for NIC FRU and reorder the I2C virtual bus
index accroding to the system silkscreen index.
