Punit Agrawal c5ee0b3104 serdev: Don't claim unsupported ACPI serial devices ... Serdev sub-system claims all ACPI serial devices that are not already initialised. As a result, no device node is created for serial ports on 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 ACPI serial devices that should not be claimed by serdev sub-system. Add the peripheral ids for Intel HS UART to the blacklist to bring back serial port on SoCs carrying them.
