nxp: Rename board/freescale/common/Kconfig to arch/Kconfig.nxp

Now that board/freescale/common/Kconfig is safe to be included once,
globally, rename this to arch/Kconfig.nxp to better reflect that it
contains options that are valid on multiple architectures and SoC
families, and not specific to NXP reference platforms either.
