[ARM] pxa: re-order platforms in Kconfig and Makefile

[ARM] pxa: re-order platforms in Kconfig and Makefile

Due to the naming mess in Kconfig and Makefile, I'd like to get them sorted
in the following order:

 1. By category:
    Intel/Marvell Dev Platforms, followed by 3rd party platforms, followed
    by end-user products (this is to ensure the commonly referenced platforms
    will appear first)

 2. By vendor name in alphabetic within each category
    (this is to ensure code reuse and similar platforms can be grouped as
     much as possible)
