I don't think it's enough. Upstream kernel doesn't accept half working
solutions. It's not only PM that needs fixing, but i2c, timer, reset handler and
possibly more. You are enabling big-endian across all tegra generations, but
tegra2 won't boot at all for example. Patches must be tested on all hw before
applying. And nit: big-endian should be enabled after all dependencies resolved.
