Merge tag 'tegra-for-4.18-memory-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/drivers

memory: tegra: Changes for v4.18-rc1

This contains some cleanup of the memory controller driver as well as
unification work to share more code between Tegra20 and later SoC
generations. Also included are an implementation for the hot resets
functionality by the memory controller which is required to properly
reset busy hardware.
