ryu: Add mainboard_init_xxx functions to get it building again
Rush has its EC on SPI, and Ryu has it on I2C, so need both
mainboard_init_ec_spi and mainboard_init_ec_i2c in both builds,
due to romstage.c being in the common tegra132 subdir.
BUG=none
BRANCH=rush_ryu
TEST=Built both rush and rush_ryu images OK. Will try to
boot on Ryu later.
