Serdev sub-system claims all serial devices that are not already

certain boards such as the Apollo Lake based UP2. This has the
unintended consequence of not being able to raise the login prompt via
serial connection.
Introduce a blacklist to reject devices that should not be treated as
a serdev device. Add the Intel HS UART peripheral ids to the blacklist
to bring back serial port on SoCs carrying them.

Thank you for addressing this long standing issue.
I am surprised there hasn't been more people complaining! Maybe even on
x86 mainline isn't that widely used on development boards.
I think it is also a case of there not being that manu x86 development
boards.
