atomisp: Fix TERM_EN_COUNT and PCI revision to enable secondary camera for CLV+

BZ: 30868

Previously the driver decides "Penwell B0" and "Non Penwell B0" simply by PCI
revision. Unfortunately CLV+ A0 has PCI revision 0x6 which is identical to
Penwell B0, thus the driver uses a wrong TERM_EN_COUNT bit definition.

This patch revised the PCI revision and TERM_EN_COUNT setting codes and make it
sure working for CLV+.
