commit f872f73601b92c86f3da8bdf3e19abd0f1780eb9 upstream.

The VCoRefLow CPU FIVR register definition for Tiger Lake is incorrect.

Current implementation reads it from MMIO offset 0x5A18 and bit
offset [12:14], but the actual correct register definition is from
bit offset [11:13].

Update to fix the bit offset.
