Doesn't /dev/console handle switching between earlycon and actual
console? I'll take a look at some point in the future.

But I can't help but notice that currently we have 5 ICC drivers built
as modules (out of 21 mentioned in the defconfig). Should we fix them
too?

CONFIG_INTERCONNECT_QCOM_MSM8916=m
CONFIG_INTERCONNECT_QCOM_MSM8996=m
CONFIG_INTERCONNECT_QCOM_QCS404=m
CONFIG_INTERCONNECT_QCOM_SM8150=m
CONFIG_INTERCONNECT_QCOM_SM8350=m
