tegra124: nyan: Keep in memory structures below 4GB.
We'd been putting some data structures like the framebuffer and the cbmem at
the end of memory, but that may not actually be addressable as identity mapped
memory. This change clamps the addresses those structures are placed at so
they stay below 4GB.
BUG=None
TEST=Booted on nyan. Went into recovery mode and verified that there was a
recovery screen. Forced memory size to be 4GB and verified that the recovery
screen still shows up.
BRANCH=None
