tegra132: use pointers in funitcfg 

Just use direct pointers to the registers in the pre-filled
data structures. In 64-bit the sizes increase, but it's small.
The fields now directly point to the correct register so no
need to do any arithmetic to identify the correct register.

BUG=chrome-os-partner:31251
BRANCH=None
TEST=Built and booted on ryu into recovery.
