Subject: [PATCH v2] arm64: defconfig: Enable SC7180 interconnect driver

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@...labora.com>

On SC7180 device trees, almost all of the nodes are declaring
interconnect properties, including the QUP nodes: at least on
some machines, leaving this configuration option disabled, or
as a module, the kernel appears to hang while initializing the
QUP node containing the UART device.

To solve this issue, enable the interconnect driver for this
SoC as built-in.
