platform/x86: pmc_atom: Fix SLP_TYPx bitfield mask

[ Upstream commit 0a90ed8d0cfa29735a221eba14d9cb6c735d35b6 ]

On Intel hardware the SLP_TYPx bitfield occupies bits 10-12 as per ACPI
specification (see Table 4.13 "PM1 Control Registers Fixed Hardware
Feature Control Bits" for the details).

Fix the mask and other related definitions accordingly.
