[PATCH] ARM: dts: aspeed: anacapa: Add MCTP I2C controller node

[Dirk Chen via B4 Relay]

From: Dirk Chen <dirkchen at amd.com>

The Facebook Anacapa BMC uses I2C5 as an MCTP (Management Component
Transport Protocol) bus. This patch enables the controller by
adding the mctp-i2c-controller node under I2C5, with multi-master
support.
