tegra132: Store ODMDATA from BCT into PMC scratch for use by kernel
In able to do earlyprintk spew on LP0 resume, the kernel needs to
know the board UART. ODMDATA (in bct/odmdata.cfg) contains this info,
and the kernel looks for it in PMC_SCRATCH20. Fetch the ODMDATA word
from the BCT copy stored in IRAM by the BootROM.
BUG=chrome-os-partner:32015
BRANCH=none
TEST=Built for Rush and Ryu OK. Dumped PMC_SCRATCH20 in TegraShell
on Rush and confirmed value is what's in odmdata.cfg.
