Just that currently I can build pch_uart without the pch_phub driver. It
seems if we were to attempt the above, the pch_uart code would then
require the pch_phub driver and the pch_phub driver would need to know
how to trigger the pch_uart code to setup the uart port again with the
new clock setting.
