ANDROID: gki_defconfig: Add qcom pcie options to gki_defconfig

The qcom PCIE support isn't able to be added as a module, so I
propose enabling CONFIG_PCIE_QCOM and CONFIG_PCIEPORTBUS in
the gki_defconfig.

For consistency, this also adds CONFIG_PCIEPORTBUS=y and RAS=y
(previously missing) to the x86 gki_defconfig
