When appending a dtb the kernel image must also be built with
CONFIG_ARM_APPENDED_DTB, which I guess is not an option we want to add
by default to Tegra and probably even less to multi_v7. So since the
kernel config needs to be changed anyway, I thought we would always
want to use tegra_defconfig as a basis for these devices.

Not that adding CONFIG_FRAMEBUFFER_CONSOLE_ROTATION to multi_v7 would
inflate the resulting kernel much, though.
