Aaron Durbin 4058d7b9d4 tegra132: refactor cpu startup code
In order to more easily bring up the 2nd core refactor
the cpu startup logic. A common 32bit_entry.S is compiled
both for romstage and ramstage to provide the common 32-bit
entry point.

BUG=chrome-os-partner:31545
BRANCH=None
TEST=Built and booted ryu to the kernel. Also, can get the 2nd
     core up out of reset.
