Subject: [PATCH 1/2] memory: tegra: Add missing dependencies

From: Thierry Reding <treding@...dia.com>

When enabling the COMPILE_TEST Kconfig option, the Tegra memory
controller can be built without ARCH_TEGRA being selected. However, the
driver implicitly depends on some symbols pulled in via ARCH_TEGRA,
which causes the build to break.

Add explicit dependencies for OF_EARLY_FLATTREE and OF_RESERVED_MEM to
the Tegra MC Kconfig option to make sure they are selected even if
ARCH_TEGRA is not.
