[PATCH v2 17/19] ARM: dts: aspeed: Add Qanta Q71L BMC machine

[Joel Stanley <joel@jms.id.au>]

From: Rick Altherr <raltherr@google.com>

The Qanta Q71L BMC is an ASPEED ast2400 based BMC that is part of a
Qanta x86 server.

This adds the device tree description for most upstream components. It
is a squashed commit from the OpenBMC kernel tree.
