Prepare to register a separate bus for the second bus.
For now, just add a new field. A latter patch will add the
bits to make it work.
This patch was generated by this script:
perl -e 'while (<>) { if (s/EM2874_I2C_SECONDARY_BUS_SELECT.*\n//) {
printf "\t\t.def_i2c_bus = 1,\n"; $found = 1; print $_ } else { if ($found) { s/^\s+// }; $found = 0; print $_; } }' \
