[PATCH 1/2] ARM: multi_v7_defconfig: Enable ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND

[Heiko Stübner]

At present on atag based legacy bootloaders, the provided kernel commandline
will be used unchanged, potentially using obscure parameters for outdated
vendor-kernel drivers.

Therefore allow them to be extended by known-good parameters from the
bootargs property of the dtb.
