x86/platform/intel-mid: Add Intel Penwell to ID table

Commit:

  ca22312dc840 ("x86/platform/intel-mid: Extend PWRMU to support Penwell")

... enabled the PWRMU driver on platforms based on Intel Penwell, but
unfortunately this is not enough.

Add Intel Penwell ID to pci-mid.c driver as well. To avoid confusion in the
future add a comment to both drivers.
