The Keystone platforms used their own keystone_defconfig mostly to
enable CONFIG_ARM_LPAE which could not be added to the multi_v7 config.
Now that we have multi_v7_lpae_defconfig/lpae.config target we can and
should use that defconfig for Keystone. Add the remaining must-have
options for Keystone support to multi_v7_defconfig.
