inteltool: Support PM registers on Cougar/Panther Point

This adds the power management register definitions for Intel's Cougar
Point and Panther Point platform controller hubs (PCH). The definitions
are actually a subset of the older ICH10R registers: I've added just
those that are mentioned in the public specifications in [1] and [2].
I've tested dumping with an H77 PCH.

NM70 is missing in [1]. Therefore, I didn't add it here.

[1] Intel 6 Series Chipset and Intel C200 Series Chipset - Datasheet
    Document-Number: 324645-006

[2] Intel 7 Series / C216 Chipset Family Platform Controller Hub (PCH) -
    Datasheet
    Document-Number: 326776-003
