Maurice Ma 1d4a9c5886 Preserve PCI some command/control register bits during enumeration ...

SBL PCI enumeration code will zero out all PCI command registers and
PCI bridge control registers. However, FSP might have programmed some
of the registers already, and some of the bits are expected to be
preserved through the PCI enumeration. This patch addressed this issue
by only clearing the bits that are required during the PCI enumeration.
