The Platform Communications Channel Table (PCCT) was defined in:
ACPI Specification Version 5.0, Errata A - Published Nov. 13, 2013.

Starting from the Acpi50.h header file, there are definitions
describing the table but a macro with the table's signature is missing.

This patch adds the definition of Platform Communications Channel
Table's signature to the relevant ACPI header files.

Notes:
    v2:
    - Replicate the definition from Acpi50.h onwards [Liming]

    v1:
    - Add definition of PCCT table signature [Krzysztof]
