soc/intel/cannonlake: Add support for UARTs on PCH-H

On PCH-H all UARTs can't be used under Windows.

As workaround add an ACPI driver for PCH-H UART2 that generates
ACPI code for the Intel LPSS ACPI driver.

Tested on Linux 5.6 with Sunrise Point ACPI ID for UART2.
Tested on Windows for all other UARTs.
