Update Ivybridge GT power meter tables

- New table for GT1
- Updates to GT2 17W table
- New table for GT2 35W SKU
- New table for GT2 Other

This also includes a workaround to poll on a different register
when deasserting force wake.  On some SKUs the kernel is hanging
when bringing up graphics unless this register is also polled.
