From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.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.

Hi Bjorn, could you pick this, as well as
https://lore.kernel.org/all/20220201200504.854917-1-nfraprado@collabora.com/,
up for arm64-defconfig-for-5.18?

Both series apply cleanly on that branch. Thanks!

Nícolas
