cr50: code modifications to support FPGA B1
The new FPGA version adds a lot of few features, while temporarily
cutting off some existing capabilities like clocking configuration
(hardwared clocks used instead), pinmux assignment for SPS interface
(hardwared connections used), etc.
This patch removes some now unused code, modifies some configuration
items and adds TODO_FGPA comment blocks highlighting code which needs
to be reviews next time FPGA version changes).
The new register definitions file is derived from hardware
description.
BRANCH=none
BUG=chrome-os-partner:43791
TEST=with these changes in place the B1 board boots to the console
prompt.
