mainboard/google/kahlee: Update PCIe port map

- Grunt moved the EMMC chip to port 2, where Kahlee had the SD reader on
PCIe port 1, so move the OemCustomize file into the variant directory.
- Add comments in baseboard version so it's easier to understand.
- Update reset pins, put the definitions in gpio.h

TEST=Build and boot Kahlee.  Build Grunt.
