[U-Boot] Orphan Freescale PowerPC boards

Hi York,

I see some orphan boards under board/freescale directory.

$ find board/freescale -name MAINTAINERS | xargs grep Orphan board/freescale/mpc8555cds/MAINTAINERS:S: Orphan (since 2014-06) board/freescale/mpc8641hpcn/MAINTAINERS:S: Orphan (since 2014-06) board/freescale/mpc8540ads/MAINTAINERS:S: Orphan (since 2014-06) board/freescale/mpc8541cds/MAINTAINERS:S: Orphan (since 2014-06) board/freescale/mx31ads/MAINTAINERS:S: Orphan (since 2013-09) board/freescale/m5253evbe/MAINTAINERS:S: Orphan (since 2014-06) board/freescale/mpc8560ads/MAINTAINERS:S: Orphan (since 2014-06)

Will you pick up the maintainership if you want to keep them?
