soc/intel/cannonlake/acpi/serialio.asl: Don't advertise unavailable devices
On PCH-H the I2C4 0:19.0 device isn't usable and thus 0:19.1 and
0:19.2 can't be detected using standard PCI probing.
Remove I2C4, I2C5 and UART2 from generic ASL code on PCH-H platforms
that advertise its PCI conformance by the _ADR attribute.
